Description

General part information

TPS7B4254 Series

For automotive off-board sensors and low-current off-board modules, the power supply is through a long cable from the main board. In such cases, protection is required in the power devices for the off-board loads to prevent the onboard components from damage during a short to GND or short to battery caused by a broken cable. Off-board sensors require a power supply as consistent as that for onboard components to secure high accuracy of data acquisition.

The TPS7B4254-Q1 device is designed for automotive applications with a 45-V load dump. The device can either be used as one tracking low-dropout (LDO) regulator or as a voltage tracker to build one closed power loop for off-board sensors with an onboard main supply. The output of the device is accurately regulated by a reference voltage at the ADJ pin.

To provide an accurate power supply to the off-board modules, the device offers a 4-mV ultralow tracking tolerance between the ADJ and FB pins across temperature. The back-to-back PMOS topology eliminates the need for an external diode under a reverse-polarity condition. The TPS7B4254-Q1 device also includes thermal shutdown, inductive clamp, overload, and short-to-battery protection to prevent damage to onboard components during extreme conditions.
