3 Description

The TPS1211-Q1 family is a 45-V, smart high-side

driver with protection and diagnostics. With wide

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

is suitable for 12-V system designs.

The device has a strong 4-A sink (PD) and source

(PU) gate driver that enables power switching using

parallel FETs in high-current system designs. Use INP

as the gate driver control input.

The device has accurate current sensing (±2

at 30 mV) output (IMON) enabling systems for

energy management. The device has integrated

two-level overcurrent protection with FLT_I output

with complete adjustability of thresholds and

response time. Auto-retry and latch-off fault behavior

can be configured. The device features remote

overtemperature protection with FLT_T output.

The TPS12111-Q1 integrates a precharge driver (G)

with control input (INP_G). This features enables

designs that must drive large capacitive loads. In

shutdown mode (EN/UVLO < 0.3 V), the controller

draws IQ of 1.7 μA.

The TPS1211-Q1 is available in a 19-pin VSSOP

package.
