MAX1232CWE

Supervisors Overview

The MAX1232CWE is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for microprocessor monitoring applications. It operates within a supply voltage range of up to 5.5 V and features a single monitored input with threshold voltages of 4.5 V and 4.75 V. The device provides active high, active low, and open drain outputs, includes manual reset capability, and incorporates a watchdog timer. It has a reset delay time of 1 s and a typical operating supply current of 200 uA. Overvoltage thresholds are specified at 4.49 V and 4.74 V. The component is housed in an SOIC-Wide-16 package and supports surface mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides multiple output configurations including active high, active low, and open drain
• Supports manual reset functionality for user-initiated control

Supervisors Applications

• Microprocessor monitoring circuits
• Voltage supervisory systems
• Power management IC applications

Supervisors Procurement Notes

Verify the specific suffix (e.g., +T) for packaging variations such as reel or cut tape when ordering. Confirm RoHS compliance status through official documentation. Check availability constraints as distribution may vary by region. Ensure the SOIC-Wide-16 package matches the design footprint requirements before procurement.

Supervisors Selection Notes

Select this component for applications requiring a single-input voltage supervisor with integrated watchdog functionality. Consider the 200 uA operating current for low-power designs. Verify that the 4.5 V and 4.75 V thresholds align with the target supply rail. The SOIC-Wide-16 package is suitable for surface mount assembly processes.

Supervisors Part Context

The MAX1232CWE belongs to the MAX1232 series of supervisory circuits from Analog Devices/Maxim Integrated. This family focuses on power management and monitoring functions. The device is categorized under PMIC - Power Management ICs and serves as a voltage supervisory solution for embedded systems requiring reliable reset generation and watchdog protection.

Supervisors Replacement Considerations

Consult official datasheets for direct pin-to-pin replacements within the MAX1232 series. Verify electrical parameters such as threshold voltages and reset delays match the original design requirements before substituting.
