Texas Instruments · Surge Protection Devices (SPDs) · VQFN-24-EP(4x4)

TPS259804ONRGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 IN power_in Input power supply connection for 2.7V to 24V operation.
2 IN power_in Input power supply connection for 2.7V to 24V operation.
3 IN power_in Input power supply connection for 2.7V to 24V operation.
4 GND power_in Ground return connection to system ground.
5 GND power_in Ground return connection to system ground.
6 EN/UVLO input High-level active enable pin with external voltage divider to IN and GND for adjustable UVLO threshold; do not leave floating.
7 ITIMER output Analog output for overcurrent blanking; external capacitor to GND sets interval duration before circuit breaker operation.
8 ILIM output Analog output for current limit setting; external resistor to GND (182Ω to 1650Ω range) sets output current limit threshold.
9 IMON output Analog load current monitor output providing 246µA/A current gain; external resistor to GND converts to voltage signal.
10 RETRY_DLY output Analog output for automatic retry delay; external capacitor to GND sets time interval between fault shutdown and restart attempts.
11 NRETRY output Analog output for retry count; external capacitor to GND sets maximum number of automatic restart attempts after fault.
12 LDSTRT input Analog input for load detection and handshake signal; external capacitor to GND sets startup verification window duration.
13 PG tri_state Digital open-drain power good output indicating FET fully enhanced and output at maximum voltage; requires external pull-up resistor.
14 GND power_in Ground return connection to system ground.
15 dVdt output Analog output for output voltage slew rate control; external capacitor to GND sets rise time during turn-on to manage inrush current.
16 IN power_in Input power supply connection for 2.7V to 24V operation; includes exposed thermal die pad connection.
17 OUT power_out Output power connection for load supply.
18 OUT power_out Output power connection for load supply.
19 OUT power_out Output power connection for load supply.
20 OUT power_out Output power connection for load supply.
21 OUT power_out Output power connection for load supply.
22 OUT power_out Output power connection for load supply.
23 OUT power_out Output power connection for load supply.
24 OUT power_out Output power connection for load supply.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
