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.
