MAX6817EUT+T

MAX6817EUT+T is a microprocessor supervisory circuit (reset/watchdog) from Maxim Integrated. It ensures a microcontroller starts reliably and remains healthy by monitoring supply voltage and a watchdog timer. If Vcc falls out of range on power-up/power-down, or if the watchdog isn’t refreshed in time, the device asserts its reset output to hold the MCU in reset. It also offers a manual reset input for external control.
Key points
- Power-on reset (POR) and reset output to the MCU (typically active-low)
- watchdog input (WDI) that must be serviced to keep reset released
- low quiescent current and operation over a wide supply range
- typically available in small packages; RoHS-compliant variants
Suffix meaning
- EUT indicates extended temperature rating
- +T indicates Tape-and-Reel packaging
Typical use
- Embedded MCUs, portable devices, sensors, and any system requiring reliable reset on power events or watchdog timeouts.

Concise features of MAX6817EUT+T (typical for the MAX6817 family):
- Single-supply operation from approximately 2.7V to 5.5V
- Power-on reset (POR) to hold MCU in reset until Vcc is stable
- Manual reset input for external reset control
- Watchdog timer with external RC timing; WDI input to refresh the timer
- Reset output (push-pull, active-low) to drive MCU reset
- Low quiescent current (suitable for battery/low-power apps)
- Small package (8-pin) for compact designs
- Tape-and-reel packaging option indicated by +T suffix
Note: Exact voltage thresholds, timing values, and temperature range can vary by variant; consult the specific MAX6817EUT+T datasheet for precise specs.

Pin count: 8 pins (SO-8 package; EUT variant). +T indicates Tape & Reel.
Function: MAX6817EUT+T is a microprocessor supervisory/reset device with a watchdog timer. It monitors Vcc and, if the supply falls out of spec or if the watchdog expires, asserts an active-low reset to the MCU. It provides a watchdog input and a reset output (among other typical supervisor pins), ensuring reliable CPU reset behavior.
