TPSI1869DH-T1-E3

TECH PUBLIC · Power Distribution Switches · SOT-363

TPSI1869DH-T1-E3 from TECH PUBLIC, in a SOT-363. 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 R2 passive Source of level-shift MOSFET Q1 (R2 node), connected to the optional external slew-rate resistor R2 (typical 0 to 100kΩ) that goes to GND.
2 D2 passive Drain of P-channel load switch Q2 (VOUT side, tied with pins 3), rated VDS -20 V with 1.3 A continuous load current.
3 D2 passive Drain of P-channel load switch Q2 (VOUT side, tied with pin 2), rated VDS -20 V with 1.3 A continuous load current.
4 S2 power_in Source of load switch Q2, the VIN input, with input voltage range up to 20 V.
5 ON/OFF input Gate control input of level-shift MOSFET Q1 that turns the switch on and off, with On/Off voltage range of 8 V maximum (1.5 V used as the on level in test conditions) and 2 kV HBM ESD.
6 R1,C1 passive Node joining the Q1 drain to the gate of Q2, where the optional pull-up resistor R1 (typical 10kΩ to 1MΩ) and slew-rate capacitor C1 (typical 1000pF) connect.
