BD73H35G-2CTR

Overview

The BD73H35G-2CTR is a Nano Energy™ overvoltage detection voltage detector manufactured by Rohm Semiconductor. It features a CMOS output type and operates within a supply voltage range of 0.8 V to 6 V. The typical threshold voltage is 3.46 V with a precision of ±1.45%. The device draws 0.27 µA in the ON state and 0.3 µA in the OFF state, supporting output currents of 1 mA (Low) and 2 mA (High). It is housed in an SSOP-5 package and qualified under AEC-Q100 Grade 1 for automotive applications.

Feature Summary

• CMOS output architecture providing high-precision voltage monitoring without hysteresis width
• Ultra-low power consumption achieved through dedicated CMOS process technology
• Automotive-grade reliability certified under AEC-Q100 standards

Applications

• Overvoltage protection circuits in automotive electronic control units
• System supervision for microcontrollers and CPUs in vehicles
• Power management monitoring in battery-operated automotive devices

Procurement Notes

Verify the specific suffix G-2CTR against the official datasheet to confirm the SSOP-5 packaging and taping quantity specifications. Ensure the application environment meets the -40°C to +125°C operating temperature range. Confirm that the 3.46 V threshold aligns with the system's overvoltage detection requirements before finalizing procurement orders.

Selection Notes

Select this component when a CMOS output is required instead of an Nch open-drain configuration found in the BD70Hxx series. The fixed 3.46 V threshold makes it suitable for systems requiring precise overvoltage monitoring at this specific level. Consider the AEC-Q100 qualification if the design targets automotive functional safety standards.

Part Context

This part belongs to the BD73Hxx-2C series of Nano Energy™ voltage detectors. It shares the same low-power CMOS characteristics and SSOP-5 form factor as other members like the BD73H38G-2CTR, differing primarily in the specific overvoltage threshold voltage setting.

FAQ

Does the BD73H35G-2CTR include a manual reset function?
