GP85210

HaloChip · AC-DC Controllers And Regulators · SOT-23-6

GP85210 from HaloChip, in a SOT-23-6. 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 GND power_in Chip ground pin for the GP85210 controller, per the pin description table on page 2.
2 FB input Output voltage feedback pin with an open-circuit voltage of 5.15 V to 5.45 V, a power-limit (OLP) threshold of 3.6 V, and a 56 ms OLP debounce delay.
3 RT input OTP threshold adjustment pin, where an NTC resistor to GND sets over-temperature protection; 10 µA flows out of RT, OTP triggers when RT is below 1 V, and protection exits above 1.15 V.
4 CS input Peak current sense pin used for cycle-by-cycle current limiting, with a internal current-limit threshold of 600 mV to 700 mV at zero duty cycle and 460 ns leading-edge blanking time.
5 VDD power_in Chip supply pin with a start-up voltage of 14.5 V to 16.5 V, undervoltage lockout threshold of 6.5 V to 8.5 V, overvoltage protection of 37 V to 40 V, and an absolute maximum rating of 35 V.
6 GATE output Gate drive output for the internal MOSFET, with a high-level output of 7.5 V minimum/typical at Io=38 mA, a clamp of 16.8 V at VDD=18 V, and an absolute maximum of 20 V.
