LTC4210-1IS6#TRPBF from Analog Devices, in a TSOT-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 | TIMER | input | Timer input pin where an external capacitor CTIMER sets a 272.9ms/µF initial timing delay and a 21.7ms/µF circuit breaker delay, and the GATE turns off whenever TIMER is pulled beyond the COMP2 threshold, such as for overvoltage detection with an external Zener. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | ON | input | ON input has a low-to-high threshold of 1.3V with 80mV hysteresis and a glitch filter, where a low level resets the LTC4210 and GATE turns on after the initial timing cycle when ON goes high. |
| 4 | GATE | output | High side gate drive for an external N-channel MOSFET, with an internal charge pump providing a 10µA pull-up current and Zener clamps to VCC and ground, and an external R-C compensation network required for current limit loop stability. |
| 5 | SENSE | input | Current limit sense input where a sense resistor between VCC and SENSE sets the analog current limit by holding SENSE 50mV below VCC in overload, and connecting SENSE to VCC disables the current limit loop and circuit breaker mode. |
| 6 | VCC | power_in | Positive supply input with an operating range of 2.7V to 16.5V, where an undervoltage lockout circuit with a glitch filter resets the LTC4210 when a low supply voltage is detected. |
