Analog Devices Inc./Maxim Integrated 5962-9326704M2A

Overview

5962-9326704M2A from Maxim Integrated Products is a military-grade monolithic silicon microprocessor supervisory circuit (device type 04), providing reset generation, watchdog timer, manual reset input, and power-fail detection for embedded systems operating from -55°C to +125°C. It features a 4.25 V to 4.50 V reset threshold, 140–280 ms reset pulse width, and 1.0–2.25 s watchdog timeout period. Designed for high-reliability avionics and defense electronics, it ensures reliable power-on and brownout reset signaling under extreme environmental stress.

For engineers reviewing the 5962-9326704M2A datasheet, 5962-9326704M2A pinout, 5962-9326704M2A application, or 5962-9326704M2A equivalent, this page delivers verified electrical specifications, MIL-PRF-38535 Class M qualification details, GDIP1-T8 package mapping, and direct alternatives with documented functional alignment and interface differences.

Technical Context

This device implements a precision voltage monitor with hysteresis for reset assertion during supply undervoltage, a programmable watchdog timer that resets the system if the WDI signal is not toggled within its timeout window, and a dedicated power-fail comparator (PFI/PFO) that asserts before VCC drops below the reset threshold. Its MR input supports external push-button reset with internal 100–600 µA pull-up current and defined logic thresholds (VIL = 0.8 V, VIH = 2.0 V).

The 5962-9326704M2A operates across 1.2 V to 5.5 V supply range with only 500 µA typical supply current, enabling use in low-power mission-critical subsystems. All outputs - RESET, WDO, and PFO - are open-drain and specified for 3.2 mA sink capability at 0.4 V max VOL, ensuring compatibility with TTL and CMOS logic families across full temperature range.

FAQ

What is the reset threshold voltage range for the 5962-9326704M2A?

The 5962-9326704M2A has a guaranteed reset threshold range of 4.25 V to 4.50 V at -55°C to +125°C, measured with ISINK = 3.2 mA on the RESET output. This specification ensures consistent brownout detection across its full military temperature range and aligns with standard 5 V supply tolerances. The 5962-9326704M2A uses internal precision bandgap references to maintain threshold stability without external components.

Does the 5962-9326704M2A include a watchdog timer function?

Yes, the 5962-9326704M2A integrates a watchdog timer with a nominal timeout period of 1.0 to 2.25 seconds. It monitors the WDI (Watchdog Input) pin and asserts the WDO (Watchdog Output) if no valid edge is detected within that window. The 5962-9326704M2A does not require external capacitors or resistors to set the timeout - it is factory-trimmed and temperature-compensated.

What package type and pin count does the 5962-9326704M2A use?

The 5962-9326704M2A uses an 8-pin hermetic dual-in-line package conforming to MIL-STD-1835 outline GDIP1-T8 (case letter P). It is a through-hole package with tin-lead leads, fully compliant with MIL-PRF-38535 Appendix A for Class M devices. Pin 6 is NC; pins 1, 7, and 8 serve MR, RESET, and WDO respectively - all open-drain outputs except MR which is an input.

How does the power-fail detection feature work on the 5962-9326704M2A?

The 5962-9326704M2A monitors the PFI (Power-Fail Input) pin against a fixed 1.20–1.30 V threshold. When the voltage on PFI drops below this level - typically set via an external resistor divider from VCC - the PFO (Power-Fail Output) pin goes active low. This allows early warning of supply decay before the reset threshold is reached. The 5962-9326704M2A specifies PFI input current ≤ ±25 nA, minimizing divider loading error.

Is the 5962-9326704M2A qualified to MIL-PRF-38535, and what class does it meet?

Yes, the 5962-9326704M2A is qualified to MIL-PRF-38535 Appendix A as a device class M microcircuit. This certification confirms vendor self-certification to non-JAN Level B requirements, including burn-in at +125°C, steady-state life testing for 1,000 hours, and full Group A–D electrical testing per method 5005 of MIL-STD-883. The 5962-9326704M2A carries the "C" compliance mark per specification.
