# LM3724IM5-4.63

**Texas Instruments** · Supervisor And Reset ICs · SOT-23-5

LM3724IM5-4.63 from Texas Instruments, 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 | GND | power_in | Ground reference. |
| 2 | GND | power_in | Ground reference; device substrate, connect to ground. |
| 3 | RESET | output | Active-low open-drain output (LM3724) that remains low while VCC is below the reset threshold voltage and for 190 ms after VCC rises above the threshold; the LM3724 requires an external pull-up resistor. |
| 4 | MR | input | Active-low manual reset input; reset is asserted whenever this pin is pulled low and remains asserted for 190 ms after MR goes high, and it may be left open. |
| 5 | VCC | power_in | Supply voltage (+5V, +3.3V, or +2.5V nominal); the VCC range is 1.0 V to 5.5 V. |
