BD73H37G-2CTR

Overview

The BD73H37G-2CTR is a Nano Energy voltage detector manufactured by Rohm Semiconductor, designed for monitoring power supply voltages in electronic circuits. It features a CMOS output type and operates within a supply voltage range of 0.8V to 6V. The device detects an over-voltage threshold with a typical value of 3.66V and maintains a precision of ±1.37%. It functions without a manual reset or watchdog timer, utilizing a push-pull/totem pole output configuration. The component is qualified under AEC-Q100 Grade 1 standards for automotive applications and operates across a temperature range of -40°C to +125°C.

Feature Summary

• AEC-Q100 Grade 1 qualified for automotive functional safety support
• Ultra-low current consumption achieved through CMOS process technology
• High-precision voltage detection with no hysteresis width

Applications

• Microcontroller system supervision
• CPU power monitoring
• DSP voltage detection

Procurement Notes

Verify the specific suffix G-2CTR against the official Rohm datasheet to confirm package type and tape-and-reel specifications. Ensure the order matches the required automotive grade qualification and operating temperature range. Confirm RoHS compliance status prior to procurement.

Selection Notes

Select this component when a fixed over-voltage detection threshold near 3.66V is required without external adjustment. The CMOS output is suitable for direct interfacing with digital logic inputs. Consider the absence of a watchdog timer if timing protection is needed.

Part Context

This part belongs to the BD73Hxx series of Nano Energy voltage detectors from Rohm. It shares the SSOP-5 package and low-power characteristics with siblings like the BD73H38G-2CTR but differs in its specific detection threshold voltage.

Replacement Considerations

The BD5210G-1TR is listed as a replacement option with similar pinout and package, though it offers adjustable delay time and different output characteristics.
