MAX706TESA+T

MAX706TESA+T is a Maxim microprocessor supervisory circuit with reset and watchdog functions. It continuously monitors the supply voltage (Vcc) and, if Vcc falls too low or the watchdog times out, it asserts a reset to the microcontroller to prevent erratic or corrupted operation. It provides a clean power-on reset at startup and a fast recovery reset during brownouts, with very low quiescent current for battery-powered designs. The device usually includes a manual-reset input and a watchdog timer, so the MCU must periodically “pet” the watchdog to keep the system active; failure to do so triggers a reset. Typical applications include microcontroller-based controllers, data loggers, portable devices, and remote sensors. The suffixes in MAX706TESA+T indicate packaging/shipping: ESA denotes the small-package variant, and +T indicates tape-and-reel packaging. For precise reset thresholds, timing, and current specs, consult the current datasheet for the exact temperature grade and package.

Here are the typical features of the MAX706TESA+T (MAX706 family, Tape & Reel, extended-temp variant):
- Microprocessor supervisor with power-on reset
- Optional watchdog timer to detect software stall
- Manual reset input
- Reset output: CMOS/TTL-compatible, active-low
- Very low quiescent current (high efficiency in battery-backed apps)
- Wide operating supply range (suitable for common MCU voltages)
- Small footprint packaging with Tape & Reel (T) option
- Extended temperature range (industrial/ automotive variants)
- Robust ESD protection
- Stable reset thresholds with timer-delay options
- RoHS-compliant, lead-free packaging
Note: Specific reset thresholds, timeout values, and exact voltage range depend on the exact MAX706 variant. For precise numbers and timing, refer to the MAX706 datasheet for the TESA+T part.

- Pin count: 8 pins (8-pin package)
- Function: Microprocessor supervisory circuit with a watchdog timer. It monitors Vcc and generates a reset output when the supply is out of range or the watchdog times out, ensuring proper CPU reset on power-up/down.

- Manufacturer: Maxim Integrated (now part of Analog Devices, Inc.)
- Company type: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits for various applications.
