TPS7B4254QDDARQ1-Texas Instruments

La description

TPS7B4254QDDARQ1 low-voltage regulator is designed and developed by Texas Instruments and is one of the automotive chips that are in great demand in the market. It is very suitable for use in many fields of automobiles, and can greatly protect on-board components from damage under extreme conditions. xt-shenzhen specializes in selling a full range of chips from Texas Instruments original factory, you can buy the electronic components you need from xt-shenzhen with confidence.

Le TPS7B4254QDDARQ1 features adjustable voltage tracking for automotive off-board sensors and low-current off-board modules, and the power supply is connected to the motherboard through a long cable. In such cases, the power device needs to provide protection for off-board loads against damage to on-board components during a short to ground or a short to battery from a broken cable. Off-board sensors require the same power supply as on-board components to ensure high accuracy in data acquisition.
The TPS7B4254QDDARQ1 can be used as a tracking low dropout (LDO) regulator or voltage tracker, creating a closed power loop for off-board sensors from the on-board mains supply. To provide accurate power to the off-board die, the device has an ultra-low tracking tolerance of 4mV over the operating temperature range between the ADJ and FB pins. The PMOS back-to-back topology eliminates the need for external diodes for reverse polarity conditions. Arrêt thermique, inductive clamping, overload, and short-to-battery protection are also included to prevent damage to onboard components under extreme conditions.
