MAX6746KA16+T

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

MAX6746KA16+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 MR input Manual-reset input, internally pulled up to VCC (12 to 28 kΩ), must be held low for at least 1 µs to assert RESET, and RESET remains asserted for the reset timeout period after MR is released.
2 SWT input Watchdog timeout input: a capacitor from SWT to GND sets tWD = 4.94 x 10^6 x CSWT (tWD in seconds, CSWT in farads), and connecting SWT to GND disables the watchdog timer.
3 SRT input Reset timeout input: a capacitor from SRT to GND sets the reset timeout period tRP = 4.94 x 10^6 x CSRT (tRP in seconds, CSRT in farads).
4 GND power_in Ground reference for the device.
5 WDS input Watchdog select input: connecting WDS to GND selects normal mode, connecting it to VCC selects extended mode that multiplies the basic watchdog timeout by 128, and a change of state on WDS clears the watchdog timer.
6 WDI input Watchdog input: a falling transition must occur within the selected watchdog timeout period or a reset pulse is generated (pulses as short as 300 ns are detected), and WDI must not be left floating, so a 100 kΩ resistor to GND is recommended when the watchdog is unused.
7 RESET output Push-pull active-low reset output that asserts when VCC or RESET IN falls below the selected threshold or when MR is pulled low, and stays low for the reset timeout period after all reset conditions clear.
8 VCC power_in Supply voltage input (1.2 V to 5.5 V operating range, 6.0 V absolute maximum) that also serves as the input for the fixed-threshold VCC monitor.
