explain
For automobile non onboard sensors and small current non onboard modules, the power supply is connected to the motherboard through a long cable. In such cases, the power supply device needs to provide protection for non board load to prevent board components from being damaged during battery short circuit caused by short circuit to ground or cable breakage. Non onboard sensors need to use the same power supply as onboard components to ensure high accuracy of data acquisition.
The TPS7B4253-Q1 device is designed for automotive applications with a 45V load drop problem. The device can be used as a low drop tracking (LDO) regulator or voltage tracker to build a closed power loop for non onboard sensors through the onboard main power supply. The output of the device is precisely regulated by the reference voltage of the ADJ pin.
In order to provide accurate power supply for non onboard modules, the device has an ultra-low tracking tolerance of 4mV between ADJ and FB pins within the operating temperature range. PMOS back-to-back topology eliminates the need for external diodes under reverse polarity conditions. TPS7B4253-Q1 device also includes thermal shutdown, inductive clamping, overload and battery short circuit protection to prevent on-board components from being damaged under extreme conditions.
