MAX706SESA+T

The MAX706SESA+T is a MAX706-series microcontroller reset supervisor from Maxim Integrated (now Analog Devices). It monitors the supply voltage, provides a robust reset to the MCU, and includes a watchdog timer to ensure the processor runs correctly. Key features typically include:
- Power-on/reset output: asserts a clean reset when Vcc is out of spec.
- Optional manual reset input for a user pushbutton.
- Watchdog input: MCU must periodically refresh to keep reset deasserted; failure triggers a reset.
- Low quiescent current and suitability for space/low-power applications.
- Available in the SESA package with Tape & Reel (+T) for automated assembly.
Use it to ensure reliable MCU startup after power-up/brownouts and to recover from faults. For exact voltage thresholds, timing, current, and pinout, consult the latest MAX706 datasheet and the SESA+T variant notes.

Equivalents (voltage‑supervisor/reset ICs) to MAX706SESA+T include:
- Analog Devices ADM706 (and ADM707 family)
- Texas Instruments TLV803 / TLV803B
- Microchip MCP1316 / MCP1317
- On Semiconductor CAT803 / CAT803A
Note: check reset thresholds, delay, and pinout; use a cross-reference to ensure packaging (SOT-23/SC‑70) and electrical specs match your design.

Key features of MAX706SESA+T (microprocessor supervisory circuit with watchdog):
- Operating voltage: typically 2.7V to 5.5V
- Automatic Power-On Reset (POR) to initialize MCU on power-up
- Built-in watchdog timer with external refresh input
- Manual reset input (active-low)
- Reset output (RESET) active-low, usually open-drain
- Reset asserted during power-down, POR, or watchdog timeout
- Very low quiescent current in normal operation
- 8-pin package (SESA) with Tape & Reel option (+T)
- Industrial temperature range (-40°C to +85°C)
Note: Exact thresholds and timing depend on the specific variant within the MAX706 family; consult the datasheet for the precise values and pinout for the SESA package.

- Pin count: 8 pins (SESA package, typical for MAX706 variants; “+T” denotes Tape & Reel).
- Function: Microprocessor supervisory / voltage-detect reset IC. It monitors Vcc and asserts a reset output on power-up/power-down/brown-out to reset the MCU.

- Manufacturer: Maxim Integrated Products, now part of Analog Devices, Inc. (ADI) after a 2021 acquisition.
- What kind of company: A global American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, including power management, supervisors, sensors, data converters, and related ICs for various markets.

MAX706SESA+T is a voltage supervisor for single-supply digital systems. It monitors Vcc and generates a reset during power-up/power-down and brown-out events, ensuring proper MCU/CPU startup. Applications include microcontrollers, DSPs, FPGAs/ASICs, and other digital ICs in embedded, automotive, industrial controls, telecom, data acquisition, and battery-powered equipment where reliable reset generation and supply monitoring are required.

Package: 6-pin SC-70 (SOT23-6). +T indicates the Tape-and-Reel version.
