In such instances, protection for the off-board loads is required in the power devices to prevent onboard components from being damaged by a short to GND or a short to battery produced by a broken cable. To ensure high accuracy of data collecting, off-board sensors require the same steady power supply as onboard components.</p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);">The <strong style="box-sizing: border-box; margin: 0px; padding: 0px;">TPS7B4253QDDARQ1</strong> is a 45-V load dump developed for automotive applications. The device can be used as a voltage tracker or as a tracking low-dropout (LDO) regulator to create a closed power loop for off-board sensors with an onboard main supply. A reference voltage at the ADJ pin correctly regulates the device's output.</p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);">The device has a 4-mV ultralow tracking tolerance between the ADJ and FB pins throughout temperature to enable an accurate power supply to off-board modules. Under reverse polarity conditions, the back-to-back PMOS topology eliminates the requirement for an external diode. Thermal shutdown, inductive clamp, overload, and short-to-battery protection are also included in the <strong style="box-sizing: border-box; margin: 0px; padding: 0px;">TPS7B4253QDDARQ1</strong> to protect onboard components during harsh situations.</p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><br style="box-sizing: border-box; margin: 0px;"/></p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><br style="box-sizing: border-box; margin: 0px;"/></p><h3 style="box-sizing: border-box; margin: 0px; padding: 0px; font-size: 14px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><strong>TPS7B4253QDDARQ1 Features</strong></h3><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><br style="box-sizing: border-box; margin: 0px;"/></p><ul class=" list-paddingleft-2" style="box-sizing: border-box; margin: 0px; padding: 0px; list-style-position: initial; list-style-image: initial; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">Reverse Polarity Protection</p></li><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">Inductive Clamp at OUT Pin</p></li><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">Current-Limit and Thermal-Shutdown Protection</p></li><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">Output Short-Circuit Proof to Ground and Supply</p></li><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">Available in the Following Packages:</p></li></ul><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"> 8-Pin SO PowerPAD Package</p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"> 20-Pin HTSSOP Package</p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><br style="box-sizing: border-box; margin: 0px;"/></p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><br style="box-sizing: border-box; margin: 0px;"/></p><h3 style="box-sizing: border-box; margin: 0px; padding: 0px; font-size: 14px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);">TPS7B4253QDDARQ1 Applications</h3><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><br style="box-sizing: border-box; margin: 0px;"/></p><ul class=" list-paddingleft-2" style="box-sizing: border-box; margin: 0px; padding: 0px; list-style-position: initial; list-style-image: initial; color: rgb(51, 51, 51); font-family: Helvetica, Arial, Tahoma, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: normal; background-color: rgb(255, 255, 255);"><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">Off-Board Sensor Supply</p></li><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">High-Precision Voltage Tracking</p></li><li><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; padding: 0px;">Power Switch for Off-Board Load</p></li></ul>
