BD5215G-2MTR

Overview

The BD5215G-2MTR is a Nano Energy adjustable delay voltage detector IC designed for automotive applications. It features an open-drain output and operates within a supply voltage range of 0.8V to 7V. The device detects a threshold voltage of 1.5V with a typical precision of ±2% or ±12mV. It includes an adjustable reset delay timer, which defaults to 55.5ms, and provides hysteresis equal to VDET x 0.05. The circuit consumes 0.23µA in the ON state and 0.27µA in the OFF state. It supports a low reset active state without manual reset or watchdog functions. The component is qualified under AEC-Q100 standards and operates between -40°C and +105°C.

Feature Summary

• Automotive-grade supervision with AEC-Q100 qualification
• Adjustable reset delay timer via external capacitor
• Ultra-low power consumption using CMOS process
• Open-drain output configuration

Applications

• Automotive system voltage monitoring
• Microcontroller reset signal generation
• Power management supervisory circuits

Procurement Notes

Verify the specific suffix '2M' against the official ROHM datasheet to confirm the exact delay time characteristics and package variant. Ensure the design accounts for the open-drain output requirements by selecting appropriate pull-up components. Confirm that the application environment remains within the specified -40°C to +105°C operating temperature range for reliable performance.

Selection Notes

Select this component when an adjustable delay function is required for voltage supervision in automotive environments. The open-drain output allows flexibility in interfacing with various logic levels. Consider the low standby current for battery-sensitive applications. Verify that the 1.5V detection threshold aligns with the target system's under-voltage protection requirements.

Part Context

This part belongs to the BD52xxG-M series of Nano Energy CMOS reset ICs. The series offers high-precision voltage detection with adjustable delay times. The BD5215G-2MTR specifically utilizes the open-drain output type (indicated by the '-2' suffix) rather than the CMOS output found in the BD53xx series. It is designed to support functional safety analysis for automotive use cases.

Replacement Considerations

BD5215G-2M is a compatible alternative with identical pinout and package.
