BD4852G-TR

Overview

The BD4852G-TR is a standard CMOS voltage detector IC manufactured by ROHM Semiconductor. It features a fixed threshold voltage of 5.2V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95V to 10V and draws a typical circuit current of 0.60μA at 4.8V. It provides an open-drain output with low-active reset signal. The component supports a reset delay timer, has no manual reset or watchdog timer functions, and operates across a temperature range of -40°C to +105°C.

Feature Summary

• CMOS technology for low power consumption
• Open-drain output configuration
• Low active reset signal generation

Applications

• Microprocessor system supervision
• Battery-powered device monitoring
• Portable equipment power management

Procurement Notes

Verify the specific suffix G-TR against official ROHM documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free characteristics as stated in the datasheet. Check for any obsolescence notices or last-time-buy statuses directly from the manufacturer before procurement planning.

Selection Notes

Select this component when a fixed 5.2V detection threshold is required for single-channel voltage monitoring. Ensure the application benefits from the low standby current and wide operating voltage range. Verify that the open-drain output interface matches the downstream logic requirements without additional pull-up components if not already present in the design.

Part Context

This part belongs to the BD48 series of standard voltage detectors from ROHM. It is designed for general-purpose supervisory applications requiring precise voltage monitoring.
