LM74700QDDFRQ1

Texas Instruments · Power Distribution Switches · TSOT-23-8

LM74700QDDFRQ1 from Texas Instruments, in a TSOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Enable input pin functioning when voltage exceeds input high threshold of 1.06V.
2 GND power_in Ground reference pin providing reference potential for device operation.
3 N.C unconnected No connection, internally unconnected.
4 VCAP output Charge pump output sourcing typical 300µA charging current to external capacitor.
5 ANODE power_in Anode and input power supply accepting 3.2V to 65V operating range, withstands -65V reverse voltage.
6 GATE output Gate drive output sourcing 11mA peak and sinking 2370mA peak to control external N-channel MOSFET gate.
7 N.C unconnected No connection, internally unconnected.
8 CATHODE input Cathode of diode and MOSFET drain connection, detects reverse current when voltage falls below -11mV relative to ANODE.
