MB3773PF-GT-BND-K5ERE1

Power Management - Specialized Overview

The MB3773PF-GT-BND-K5ERE1 is a power supply monitor integrated circuit manufactured by Infineon Technologies. It operates within a supply voltage range of 3.5 V to 16 V and features a threshold voltage of 4.2 V with an overvoltage threshold of 4.4 V. The device includes a watchdog timer and provides a reset delay time of 100 ms. It draws a working supply current of 600 uA and dissipates up to 200 mW. The component supports open collector outputs and is housed in an SOP-8 package for surface mount installation.

• Supports surface mount installation in compact packages

Power Management - Specialized Applications

• Embedded system power supervision
• Microcontroller reset generation
• Industrial control unit monitoring

Power Management - Specialized Procurement Notes

Verify the exact suffix K5ERE1 against official Infineon documentation, as suffixes often denote specific tape-and-reel packaging or regional variants rather than functional changes. Confirm lifecycle status, as this part may be obsolete or discontinued. Ensure compatibility with SOP-8 footprint requirements and validate operating temperature ranges for your specific environment before procurement.

Power Management - Specialized Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. Ensure the 4.2 V threshold aligns with the monitored rail. Consider the 600 uA quiescent current for low-power designs. Verify that the SOP-8 package fits the PCB layout constraints and that the open collector output suits the downstream logic interface requirements.

Power Management - Specialized Part Context

This part belongs to the MB3773 series of supervisory circuits from Infineon Technologies. It falls under the PMIC - Power Management ICs category, specifically designed for voltage monitoring applications. The series typically offers various threshold options and package configurations to suit different embedded design needs.

Power Management - Specialized Replacement Considerations

Check for direct substitutes within the MB3773 family or comparable PMIC monitors from other manufacturers. Verify pinout compatibility and electrical parameter equivalence, particularly threshold voltages and watchdog timing characteristics, before considering alternative components.
