BD4832G-TR

Overview

The BD4832G-TR is a standard CMOS voltage detector IC manufactured by ROHM Semiconductor. It features a single input monitoring circuit with an open-drain output type and no manual reset or watchdog timer capabilities. The device operates within a supply voltage range up to 10 V and provides a typical under-voltage detection threshold of 3.2 V with ±1% precision. It supports a reset active voltage range from 0.95 V to 10 V and includes a hysteresis voltage defined as Vs x 0.05. The component is housed in an SSOP-5 package, measures 2.9x2.8 mm with a thickness of 1.25 mm, and functions across a temperature range of -40°C to +105°C.

Feature Summary

• CMOS technology for low power consumption
• Open-drain output configuration
• High accuracy voltage detection
• Compact surface-mount packaging

Applications

• Portable equipment power management

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be classified as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that some suppliers may indicate limited stock or discontinuation. Ensure the ordering part number matches the specific suffix requirements for tape-and-reel packaging. Cross-reference datasheets for any updates regarding RoHS compliance or environmental regulations.

Selection Notes

Select this component when a fixed 3.2 V threshold is required for system supervision. Consider the open-drain output compatibility with downstream logic levels. Evaluate the operating temperature range against environmental conditions. Compare performance metrics such as hysteresis and reset delay with alternative supervisory ICs if adjustable thresholds are needed.

Part Context

This part belongs to the BD48 series of standard voltage detectors from ROHM Semiconductor. It is designed for applications requiring reliable power monitoring in compact form factors. The series typically offers various threshold voltages to suit different supply rail requirements while maintaining consistent package dimensions and electrical characteristics across the family.

Replacement Considerations

The BD5232G-1 is documented as a replacement option with the same SSOP-5 package. Verify functional differences such as adjustable delay timers and lower circuit current in the substitute. Ensure pinout compatibility and reset active state alignment during integration.
