MT9700

Aerosemi · Power Distribution Switches · SOT-23-5

MT9700 from Aerosemi, in a SOT-23-5. 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 VOUT power_out Power-switch output, which is the drain of the internal MOSFET; current flows from VIN to VOUT toward the load, and the reverse-current blocking feature prevents current flowing from VOUT to VIN when the device is disabled.
2 GND power_in Ground connection that must be connected externally to the power PAD.
3 SET passive External resistor from SET to ground sets the current-limit threshold; RSET of 6.8kΩ gives a current limit of 1 A per the electrical characteristics, and SET voltage is limited to -0.3V to (VIN+0.3V).
4 EN input Enable input where logic high turns on the power switch; VIL is 0.8 V max and VIH is 2 V min for VIN = 2.5 V to 5.5 V, and EN voltages are limited to -0.3V to (VIN+0.3V).
5 VIN power_in Input voltage with an operating range of 2.4 V to 5.5 V, requiring a 10 µF or greater ceramic capacitor from VIN to GND placed as close to the IC as possible.
