LM66100DCKT

Texas Instruments · Power Distribution Switches · SC-70-6

LM66100DCKT from Texas Instruments, in a SC-70-6. 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 VIN power_in Device input; the recommended input voltage range is 1.5 V to 5.5 V, and the absolute maximum input voltage range is -6 V to 6 V.
2 GND power_in Device ground.
3 CE input Active-low chip enable that can be connected to VOUT for reverse current protection; do not leave floating, the recommended CE pin voltage range is 0 V to 5.5 V and the absolute maximum CE pin current is -1 mA.
4 N/C unconnected Not internally connected; can be tied to GND or left floating.
5 ST output Active-low open-drain status output that is pulled low when the chip is disabled and high-impedance when enabled; connect to GND if not required, with a recommended ST pin voltage range of 0 V to 5.5 V and an absolute maximum ST pin current of -1 mA.
6 VOUT power_out Device output; the recommended output voltage range is 1 V to 5.5 V.
