BD5355G-TR

Overview

The BD5355G-TR is a CMOS voltage detector IC from the BD53xx series by ROHM Semiconductor. It features a fixed detection threshold voltage of 5.5V with a precision of ±1%. The device operates within a supply voltage range of 0.95V to 10V and consumes ultra-low current, typically 0.85µA at Vdet=4.8V. It provides a CMOS output type with an active low reset signal. The delay time is controlled by an external capacitor. The component is housed in a compact SSOP5 package (2.9mm x 2.8mm x 1.25mm) and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Ultra-low current consumption for extended battery life
• High accuracy detection voltage with ±1% precision
• Delay time adjustable via external capacitor connection
• Compact SSOP5 package suitable for space-constrained designs

Applications

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

Procurement Notes

Verify the specific suffix 'G-TR' against the manufacturer's latest datasheet to confirm the tape-and-reel packaging configuration. Ensure the order quantity aligns with the standard minimum packing quantity of 3000 units if applicable. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to finalizing procurement plans.

Selection Notes

Select this component when a fixed 5.5V threshold is required for system supervision. It is suitable for applications needing precise voltage monitoring without adjustable thresholds. Consider the external capacitor requirement for delay timing. Compare current consumption and package size against alternatives like the BD52xx series if open-drain output is preferred instead of CMOS.

Part Context

The BD5355G-TR belongs to the BD53xx series of free delay time setting CMOS voltage detector ICs. This series is designed for high accuracy and low power consumption. It complements the BD52xx series, which offers N-channel open drain outputs. Both series share similar package options and operational characteristics, differing primarily in output stage configuration.

Replacement Considerations

The BD5250G-1TR is listed as a replacement option with a similar pinout and package. Note that the BD5250G-1TR has a different detection voltage (5.0V) and uses an N-channel open drain output, whereas the BD5355G-TR uses CMOS output. Verify functional compatibility before substitution.

FAQ
