Overview
The MAX6332UR23D3+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supply voltages in the 1.8V to 3.3V range for microprocessor and digital systems. The device features an active-high push/pull RESET output, triggered when the input voltage drops below a preset threshold of 2.3V. It operates within a temperature range of -40°C to +125°C and is housed in a SOT-23-3 surface-mount package.
Feature Summary
- Monitors power supply voltage to ensure system reliability
- Provides active-high reset signal via push/pull output
- Eliminates need for external components and adjustments
Applications
- Microprocessor (µP) supervisory circuits
- Digital system power monitoring
- Voltage supervision in low-voltage applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure the ordering suffix matches the required tape-and-reel packaging configuration. Validate that the active-high output variant aligns with the target circuit design before procurement.
Selection Notes
Select this part when an active-high reset signal is required for the application logic. The fixed 2.3V threshold suits systems operating near the lower end of the standard voltage range. Compare against MAX6333 variants if an active-low output is preferred instead. Ensure the SOT-23-3 package fits the available PCB footprint constraints.
Part Context
This component belongs to the MAX6332/MAX6333/MAX6334 family of ultra-low-voltage, low-power µP reset circuits. While functionally similar regarding voltage monitoring, the MAX6332 is distinguished by its active-high output, whereas the MAX6333 provides an active-low push/pull output and the MAX6334 offers an active-low open-drain output.
