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 3.7-A peak source (PU) and

4-A peak sink (PD) 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 system designs

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 a total shutdown current of 0.9 μA (typical).

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

package with a pin removed between adjacent high

voltage and low voltage pins, providing 0.8-mm

clearance.
