BD5353G-TR

Overview

The BD5353G-TR is a CMOS voltage detector IC from the BD53xx series by ROHM Semiconductor. It features a fixed detection threshold of 5.3V with ±1% precision and an adjustable delay time controlled by an external capacitor. The device utilizes a 5-pin SSOP package (2.90mm x 2.80mm x 1.25mm) and operates within a supply voltage range of 0.95V to 10V. It draws ultra-low current consumption of 0.85µA at VDET=4.8V and supports an operating temperature range of -40°C to 105°C.

Feature Summary

• Adjustable reset delay time via external capacitor connection
• High accuracy detection voltage with ±1% tolerance
• Ultra-low current consumption for battery-powered applications
• CMOS output type providing active low reset signal

Applications

• Microcontroller system reset circuits
• Logic circuit power supervision
• Battery-operated device monitoring

Procurement Notes

Verify the specific suffix G-TR against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the application circuit includes the required external capacitor for delay adjustment, as the delay time is not internally fixed. Confirm RoHS compliance status matches project requirements.

Selection Notes

Select this component when a fixed 5.3V threshold is required with customizable reset timing. Compare against BD52xx series if open-drain output is preferred instead of CMOS. Consider the SSOP5 package size constraints relative to available PCB space and thermal dissipation needs in the target environment.

Part Context

This part belongs to the BD53xx series of free delay time setting CMOS voltage detectors. It shares family characteristics such as ultra-low current consumption and capacitor-controlled delay with other variants like BD5355 and BD5357, differing primarily in the fixed detection voltage threshold.

Replacement Considerations

BD5250G-1 is listed as a recommended replacement with the same pinout and package, though it features an N-channel open drain output instead of CMOS.
