Detailed Description

5V microprocessor supervisory IC with watchdog timer, manual reset, battery-backup switchover for SRAM, power-fail monitor (PFI/PFO), and memory write protection (CE gating). Provides clean resets on power-up, power-down, and brownout, with complementary reset outputs for easy interface to different logic requirements. Designed to increase system reliability while reducing component count.

Key Features

Precise 5V supply monitoring with an accurate reset threshold suited for 5V systems

Clean, timed reset on power-up, power-down, and brownout

Watchdog timer (WDI) to catch software lockups

Manual reset input (MR) for user/host-initiated resets

Complementary reset outputs (active-low and active-high) for flexible interfacing

Battery-backup switchover to keep SRAM powered when VCC fails

Chip-enable (CE) gating to prevent erroneous writes to memory during brownout

Power-fail comparator (PFI/PFO) for early warning/interrupt before shutdown

Low quiescent current to minimize system power

Available in DIP and SOIC package options for through-hole or SMT builds

Key Advantages

Improves system uptime with reliable, glitch-free resets

Protects critical data in battery-backed SRAM during power loss

Catches software faults automatically with the watchdog

Reduces BOM and board space by integrating multiple supervisory functions

Speeds time to market with a proven, widely used supervisor family

Flexible I/O (RESET/RESET, MR, PFI/PFO, CE gating) simplifies design across many platforms

Packaging

Type: Through-hole PDIP-16 (Dual In-line, 16 pins); supplier package code reference: 6283

Material: Molded epoxy package body; matte Sn or SnPb terminal finish options depending on RoHS variant

Size: Body width ~0.300 in (7.62 mm); pin pitch 2.54 mm; row spacing 7.62 mm; standard 16-lead DIP footprint

Pin configuration (typical functions): VCC, GND, RESET (active low), RESET (active high), MR (manual reset), WDI (watchdog input), PFI (power-fail input), PFO (power-fail output), CE IN / CE OUT (memory write-protect gating), BATT/VBATT (battery input), VOUT/VBACKUP (battery-backed memory rail), and related control pins. Refer to datasheet for exact pinout.

Thermal characteristics: Typical PDIP θJA on a standard board ~80–100°C/W (airflow and layout dependent)

Electrical properties (typical): 5V rail monitoring; accurate 5V reset threshold; low supply current; CMOS/TTL-compatible resets; watchdog and reset timeouts provided internally. See datasheet for exact limits and timing.

Lifecycle

Status: Active, widely used supervisor IC from Analog Devices (Maxim Integrated). Not considered near end-of-life at the time of writing. Check the latest status on our website or via ADI PCN/PDN notices.

Same-family and close alternatives (verify features, thresholds, and pinouts before use):

- MAX705: Similar function set for 5V rails; different reset output configuration

- MAX707: Similar, with a lower reset threshold option for 5V systems

- MAX708: Similar, lower threshold with complementary reset outputs

- MAX690 / MAX692 / MAX694: Related supervisor families with battery-backup and watchdog features

- ADM690 / ADM692 / ADM694 (Analog Devices): Functionally similar supervisors from ADI heritage portfolio

- Other brands offer supervisors (e.g., TI TPS33xx/TPS38xx series, Microchip MCP13xx series), but many lack integrated CE gating and battery-backup SRAM control—review carefully
