CAT1832Z-GT3

Supervisors Overview

The CAT1832Z-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a manual reset capability alongside an integrated watchdog timer. The device provides active low push-pull outputs and includes a reset delay time of 1 second. It supports threshold voltages of 3.3 V and 5 V, with over-voltage thresholds specified at 2.64 V and 2.97 V. The component functions reliably across a temperature range from -40 C to +85 C and consumes a working supply current of 35 uA. It is housed in an MSOP-8 surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset functionality for user-initiated control
• Provides active low push-pull output configuration
• Operates with low quiescent current consumption

Supervisors Applications

• Power supply supervision in embedded systems
• Microcontroller reset management
• Industrial control unit monitoring
• Consumer electronics power integrity verification

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance details via official documentation. Check regional shipping restrictions as availability may vary. Ensure compatibility with existing board layouts given the MSOP-8 package dimensions. Validate electrical parameters against specific application requirements before integration.

Supervisors Selection Notes

Consider the fixed threshold voltages and lack of programmability when designing circuits requiring precise reset levels. Evaluate the 1-second reset delay against system startup timing requirements. Assess the single-input monitoring capability against multi-rail architectures. Verify the absence of battery backup switch functionality if standby power preservation is critical. Confirm temperature range suitability for the intended operating environment.
