TPS25940LRVCR

Texas Instruments · Surge Protection Devices (SPDs) · WQFN-20-EP(3x4)

TPS25940LRVCR from Texas Instruments, in a WQFN-20-EP(3x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DEVSLP input Active high DevSleep mode control; high voltage activates low-power DevSleep mode.
2 PGOOD output Active high power good open drain output; goes high when PGTH crosses threshold value.
3 PGTH input Positive input of PGOOD comparator.
4 OUT output Power output of the device.
5 OUT output Power output of the device.
6 OUT output Power output of the device.
7 OUT output Power output of the device.
8 OUT output Power output of the device.
9 IN power_in Power input and supply voltage of the device, 2.7V to 18V operating range.
10 IN power_in Power input and supply voltage of the device, 2.7V to 18V operating range.
11 IN power_in Power input and supply voltage of the device, 2.7V to 18V operating range.
12 IN power_in Power input and supply voltage of the device, 2.7V to 18V operating range.
13 IN power_in Power input and supply voltage of the device, 2.7V to 18V operating range.
14 EN/UVLO input Programmable undervoltage lockout threshold setting; when pulled to GND resets fault latch in TPS25940L.
15 OVP input Programmable overvoltage protection threshold setting input.
16 GND power_in Ground; must be connected to exposed PowerPAD using multiple vias for good thermal performance.
17 ILIM bidirectional Current limit control; resistor from this pin to GND sets overload and short-circuit current limit.
18 dVdT bidirectional Output voltage slew rate control; capacitor from this pin to GND sets ramp rate.
19 IMON output Current monitor output; sources scaled down ratio of current through internal FET, resistor to GND converts to proportional voltage.
20 FLT output Fault indicator open drain output; goes low for Undervoltage, Overvoltage, Reverse voltage, or Thermal shutdown event.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
