BD5216G-2CGTR

Overview

The BD5216G-2CGTR is a Nano Energy™ CMOS voltage detector IC featuring an adjustable delay timer controlled by an external capacitor. It offers a typical under-voltage detection voltage of 1.6V with ±3% precision and a reset active voltage range of 0.8V. The device utilizes an N-channel open-drain output type, operates within a supply voltage range up to 7V, and maintains low circuit current consumption of 0.23µA (ON) and 0.27µA (OFF). It supports an operating temperature range from -40°C to 125°C and is housed in an SSOP5 package.

Feature Summary

• Adjustable delay time setting via external capacitor
• High-precision voltage detection with low power consumption
• Automotive-grade reliability with AEC-Q100 qualification

Applications

• Automotive electronic control unit monitoring

Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm functional safety classification requirements for automotive integration. Ensure external capacitor selection aligns with desired delay timing specifications. Check RoHS compliance status against project environmental standards. Validate supply availability through authorized distribution channels.

Selection Notes

Select this component when precise voltage threshold monitoring at 1.6V is required alongside customizable reset delays. The open-drain output suits interfacing with various logic families. Consider the wide operating temperature range for harsh environments. Evaluate the low standby current for battery-sensitive applications. Compare against fixed-delay alternatives if timing flexibility is not needed.

Part Context

This part belongs to ROHM's Nano Energy™ series of CMOS voltage detectors designed for high efficiency and compact designs. The BD52xx-2C series specifically provides N-channel open-drain outputs, distinguishing it from the CMOS output BD53xx variants. These devices are engineered for automotive and industrial applications requiring reliable power management and system reset functions.

Replacement Considerations

BD5216G-2MTR serves as a similar level replacement with identical pinout and package. BD5214G-2CGTR and BD5218G-2CGTR offer alternative detection voltages within the same family. Verify compatibility regarding detection voltage tolerance and delay circuit requirements before substitution.
