MIC803-29D4VC3-TR

Microchip · Supervisor and Reset ICs · SC-70-3

MIC803-29D4VC3-TR from Microchip, in a SC-70-3. 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 GND power_in Device ground reference. Connect to system ground (0V).
2 /RESET output Active-low, open-drain reset output. Asserts low when VCC falls below the reset threshold VTH (2.93V nominal for the -29 option) and remains asserted for one reset timeout period (1120 ms min for the D4 option) after VCC rises back above VTH. Requires an external pull-up resistor (typ. 100 kΩ) to VCC or another supply ≤5.5V. Guaranteed valid with VCC as low as 1.0V. VOL ≤ 0.4V at ISINK = 3.2 mA (VCC ≥ 4.0V); VOL ≤ 0.3V at ISINK = 1.2 mA (VCC ≥ 2.5V); leakage ≤1 µA when deasserted. Max output current 20 mA.
3 VCC power_in Power supply input and monitored voltage. Operating range +1.0V to +5.5V (absolute max +6.0V). Typical supply current 4.5 µA at 3.6V. A 0.1 µF bypass capacitor close to this pin is recommended for additional transient immunity.
