BU4847G-TR

Supervisors Overview

The BU4847G-TR is a CMOS voltage detector IC manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a single input channel with a typical threshold voltage of 4.7 V and an accuracy of ±1%. The device operates within a supply voltage range of 0.7 V to 7 V and draws a static current of 550 nA. It utilizes an open-drain output type and lacks manual reset or watchdog timer functions. The component is housed in a compact SSOP-5 package and supports operation across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• CMOS technology ensures low power consumption with minimal static current draw during operation.
• Single-channel monitoring capability provides precise detection of under-voltage conditions.
• Open-drain output configuration allows flexible interfacing with various logic levels.
• Compact SSOP-5 packaging facilitates surface-mount installation in space-constrained designs.

Supervisors Applications

• Power supply supervision in portable electronic devices
• Monitoring battery voltage levels in mobile systems
• System reset generation in microcontroller-based circuits
• Voltage level detection in industrial control modules

Supervisors Procurement Notes

Verify the specific suffix 'G-TR' to confirm the reel packaging format and RoHS compliance status. Confirm that the part number matches the exact threshold voltage requirement of 4.7 V. Check for any obsolescence notices or end-of-life declarations from the manufacturer before finalizing procurement plans. Ensure compatibility with the intended SSOP-5 footprint on the PCB layout.

Supervisors Selection Notes

Select this component when a low-power, single-channel voltage detector with a 4.7 V threshold is required. Consider the open-drain output if external pull-up resistors are acceptable in the design. Evaluate the operating temperature range to ensure suitability for the target environment. Compare against similar parts in the BU48xx series if different threshold voltages or output types are needed.

Supervisors Part Context

The BU4847G-TR belongs to the BU48xx series of standard voltage detectors from ROHM Semiconductor. This series is characterized by its CMOS construction, offering high reliability and low current consumption. The device is part of a broader family of supervisory ICs used for power management and system protection in various electronic applications.
