Texas Instruments TPS1210-Q1 Smart High Side Driver
Texas Instruments TPS1210-Q1 Smart High Side Driver is a 45V, low IQ, back-to-back MOSFET driver with a 3.5V to 40V operating voltage range. This driver is designed to withstand and protect the loads from negative supply voltages down to -40V. The TPS1210-Q1 driver includes two strong (2A) gate drivers with separate control inputs (INP1 and INP2) to drive back-to-back MOSFETs in a common source configuration. This driver is available in a 19-pin VSSOP package (5.1mm x 3mm). The TPS1210-Q1 driver is AEC-Q100 qualified for automotive applications.
The TPS1210-Q1 driver features an integrated 11V charge pump, high or low-side current sense configuration, and low 1.5μA shutdown current (EN/UVLO =Low). This driver offers adjustable input Undervoltage Lockout (UVLO) and adjustable short-circuit protection functions. The TPS1210-Q1 driver is used in applications such as DC-DC converters and automotive 12V BMS.
