MAX16002BTC+

Supervisors Overview

The MAX16002BTC+ is a low-voltage, quad-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent voltage rails and provides reset signals when thresholds are exceeded. The device operates within a supply voltage range of up to 5.5 V and features an adjustable threshold voltage alongside fixed options at 1.8 V and 3.3 V. It includes a manual reset input and a watchdog timer function. The output type is active low with an open-drain configuration, and the reset delay time is specified at 200 ms. The accuracy is rated at 2.5%. The component is housed in a TQFN-12 surface-mount package and supports operation temperatures from -40°C to +125°C.

Supervisors Feature Summary

• Monitors four independent voltage inputs for system integrity
• Integrates a watchdog timer for fault recovery
• Supports manual reset functionality via dedicated input
• Provides active low open-drain reset outputs

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Microprocessor reset generation in industrial controllers
• Voltage supervision in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix 'BTC' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status through current documentation as regulatory updates may occur. Check availability status with authorized distributors since some listings indicate limited supply or regional restrictions. Ensure the TQFN-12 package dimensions align with your PCB footprint constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple voltage rails with high accuracy. The adjustable threshold option allows flexibility for non-standard voltage levels. Consider the wide operating temperature range for harsh environments. The integrated watchdog timer simplifies software reliability mechanisms. Verify that the 200 ms reset delay meets your system startup timing requirements. Ensure the open-drain output compatibility with your target logic levels.
