MAX6753KA29+T

Maxim Integrated · Monitors & Reset Circuits · SOT-23-8

MAX6753KA29+T from Maxim Integrated, in a SOT-23-8. 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 SET0 input Logic input that, together with SET1, selects the fast watchdog window ratio (8, 16 or 64) or disables the watchdog when SET0 is high and SET1 is low; VIL is 0.8V max and VIH is 2.4V min at VCC ≥ 4.0V.
2 SWT passive Connect a low-leakage (<10nA, ceramic recommended) capacitor from SWT to GND to set the slow watchdog period tWD2 = 0.65 x 10^9 x CSWT (tWD2 in seconds, CSWT in farads).
3 SRT passive Connect a capacitor from SRT to GND to set the reset timeout period tRP = 4.94 x 10^6 x CSRT (tRP in seconds, CSRT in farads); the capacitor must be low-leakage (<10nA).
4 GND power_in Ground reference for the device.
5 SET1 input Logic input that, together with SET0, selects the fast watchdog window ratio or disables the watchdog timer (SET0 high and SET1 low disables it); VIL is 0.8V max and VIH is 2.4V min at VCC ≥ 4.0V.
6 WDI input Watchdog input; falling transitions faster than tWD1 or slower than tWD2 force RESET low for the reset timeout period, the pin has a 300ns minimum pulse width and must not be left floating (use a 100kΩ resistor to ground if the watchdog is unused).
7 RESET output Active-low reset output that asserts when VCC or RESET IN falls below its threshold or on manual reset and stays low for the reset timeout period after release; on the MAX6753 it is an open-drain output with a maximum rating of 6.0V to GND.
8 VCC power_in Supply voltage input and fixed-threshold VCC monitor, specified for 1.2V to 5.5V operation (1.0V minimum at TA = 0°C to +125°C) with a 6.0V absolute maximum.
