MAX6303CSA+

Analog Devices Inc./Maxim Integrated · Supervisor And Reset ICs · SOIC-8

MAX6303CSA+ from Analog Devices Inc./Maxim Integrated, in a SOIC-8. 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 RESET IN input High-impedance reset comparator input connected to an external resistor divider to set the threshold, VRST = 1.22 x (R1 + R2)/R2 (1.22V nominal input threshold).
2 GND power_in Ground.
3 SRT passive Set reset-timeout input; a capacitor to ground sets tRP = 2.67 x CSRT (CSRT in pF, tRP in µs).
4 SWT passive Set watchdog-timeout input; a capacitor to ground sets tWD = 2.67 x CSWT (pF to µs), and connecting it to ground disables the watchdog.
5 WDS input Watchdog-select input; GND selects normal mode and VCC selects extended mode with the timeout multiplied by 500.
6 WDI input Watchdog input; a rising or falling transition must occur within the watchdog timeout period or a reset pulse occurs.
7 RESET output Push-pull active-low reset output (MAX6303) that goes low when VIN drops below VRST, stays low for the reset timeout period after VIN exceeds VRST, and pulses on watchdog timeout; guaranteed low at VCC of 1V or above.
8 VCC power_in Supply voltage, bypassed to ground with a 0.1µF capacitor placed close to the pin.
