3 Description

The TPS1210x-Q1 family is a 45-V, low IQ, smart high

side driver with protection and diagnostics. With wide

operating voltage range of 3.5 V – 40 V, the device

is designed for 12-V system designs. The device can

withstand and protect the loads from negative supply

voltages down to –40 V.

The device has two strong (2-A) GATE drivers with

separate control inputs (INP1, INP2) to drive backto-

back MOSFETs in common source configuration.

TPS12100-Q1 has active high control inputs and

TPS12101-Q1 has active low control inputs.

The device provides adjustable short-circuit

protection. Auto-retry and latch-off fault behavior can

be configured. Current sensing can be done either

by an external sense resistor or by MOSFET VDS

sensing. High side or low side current sense resistor

configuration is possible by using CS_SEL pin input.

The device also features diagnosis of the internal

short circuit comparator using external control on

SCP_TEST input.

Low Quiescent current 35 μA (typical) in operation

enables always ON system designs. Quiescent

current reduces to 1.5 μA (typical) with EN/UVLO low.

The TPS1210x-Q1 is available in a 19-pin VSSOP

package.
