TPS23525PWR

Texas Instruments · Supervisor And Reset ICs · TSSOP-16

TPS23525PWR from Texas Instruments, in a TSSOP-16. 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 Neg48A input Input to the OR-ing controller for the -48A feed; the TPS23525 regulates the drop from VEE to Neg48A to 25 mV to mimic an ideal diode.
2 NC unconnected No connect to space high-voltage pins.
3 GATEB output Gate driver for the OR-ing FET of the -48V_B feed.
4 GATEA output Gate driver for the OR-ing FET of the -48V_A feed.
5 VEE power_in IC ground; Kelvin sense to the bottom of RSNS to ensure accurate current limit.
6 SNS input Sense pin used to measure and regulate current; Kelvin sense to RSNS to ensure accurate current limits.
7 GATE output Gate drive for the main hot swap FET.
8 SS output Soft-start pin; connect a capacitor CSS between SS and -48V_OUT, as the dv/dt on -48V_OUT is proportional to the gate sourcing current divided by CSS.
9 D input Senses the drain of the hot swap FET and programs the threshold where the hot swap switches between CL1 and CL2; connect a resistor from this pin to the hot swap FET drain (-48V_OUT). Recommended RD is 120 kΩ to 2,000 kΩ.
10 TMR output Timer pin that programs the duration the hot swap FET can be in current limit; program it with a capacitor between TMR and VEE.
11 OV input Input overvoltage comparator; a resistor divider programs the threshold at which the device turns off on an overvoltage event.
12 UVEN input Input undervoltage comparator; a resistor divider programs the threshold at which the device turns on.
13 VCC power_out Clamped supply; tie to RTN through a resistor (VCC absolute maximum 20 V with current into VCC below 10 mA).
14 PGb output Power Good Bar, an open-drain output that goes low when the hot swap is fully on and the DC/DC can draw full power.
15 NC unconnected No connect to space high-voltage pins.
16 Neg48B input Input to the OR-ing controller for the -48B feed; the TPS23525 regulates the drop from VEE to Neg48B to 25 mV to mimic an ideal diode.
