TPS2331IPWR

Texas Instruments · Supervisor And Reset ICs · TSSOP-14

TPS2331IPWR from Texas Instruments, in a TSSOP-14. 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 GATE output Connects to the gate of the external N-channel high-side MOSFET; the charge pump sources about 15 μA and generates 9 V-12 V gate-to-source across the MOSFET.
2 DGND power_in Digital ground for the device.
3 TIMER output A capacitor on TIMER sets how long the power switch may stay in overcurrent before latching off, and a minimum 50-pF capacitor to ground is strongly recommended in high-power or high-temperature applications to prevent false triggering.
4 VREG output Output of the internal low-dropout regulator, less than 5.5 V, which requires a 0.1-μF ceramic bypass capacitor to ground for noise rejection and stable operation.
5 VSENSE input Power-good sense input that pulls PWRGD low when the voltage sensed is below the reference of approximately 1.23 V.
6 AGND power_in Analog ground, to be connected to DGND as close as possible.
7 ISENSE input Current-sense input connected to the MOSFET drain; an overcurrent condition is assumed when ISENSE is pulled below ISET, and ISENSE and ISET must never exceed VI(IN).
8 IN power_in Input supply that powers the device and should be connected to the power source driving the external MOSFET; the device supports 3-V, 5-V, or 12-V operation within a 3 V to 13 V input range.
9 AGND power_in Analog ground, to be connected to DGND as close as possible.
10 ISET input Sets the circuit-breaker threshold through an external resistor connected to IN, with an internal 50-μA current source drawn from this pin and VI(ISET) never exceeding VI(IN).
11 FAULT output Open-drain overcurrent fault flag that goes low and latches the device off when TIMER reaches 0.5 V; the device restarts only after ENABLE is toggled or input power is cycled.
12 PWRGD output Open-drain power-good output that is pulled low when VSENSE is below about 1.23 V, with a 20-μs deglitch filter and pulled up to its pull-up rail in disable mode.
13 ENABLE input Active-high enable input on the TPS2331 (active-low on the TPS2330); pulling it to the disabled state for more than 50 μs discharges the gate at a controlled rate and enables the output discharge transistor.
14 DISCH output Connects to the source of the external N-channel MOSFET to discharge the load when the MOSFET is disabled, and also serves as the reference for the internal gate-voltage clamp.
