BD5359G-TR

Overview

The BD5359G-TR is a CMOS voltage detector IC from the BD53xx series by ROHM Semiconductor. It features an adjustable delay time controlled by an external capacitor and provides a CMOS output type. The device offers high accuracy detection voltage with a typical precision of ±1%. Key electrical parameters include a typical under-voltage detection voltage of 5.9V, a reset active voltage range of 0.95 to 10V, and ultra-low current consumption of 0.85µA at VDET=4.8V. The hysteresis voltage is defined as VDET x 0.05. It operates within a temperature range of -40°C to 105°C and is housed in an SSOP5 package measuring 2.9x2.8mm.

Feature Summary

• Adjustable delay time functionality controlled via an external capacitor connection
• CMOS output configuration providing push-pull drive capability
• High accuracy detection voltage with ±1% precision tolerance

Applications

• Microcontroller circuit reset generation
• Logic circuit power supply monitoring
• System supervision requiring specific delay timing

Procurement Notes

Verify the specific ordering suffix TR for tape-and-reel packaging when sourcing. Confirm the exact detection voltage variant required, as the BD53xx series includes multiple fixed voltage options. Ensure the application design accommodates the external capacitor needed for the adjustable delay feature. Check RoHS compliance status if restricted substances are a constraint for the target market.

Selection Notes

Select this component when a CMOS output is preferred over open-drain types found in the BD52xx series. The adjustable delay feature distinguishes it from fixed-delay detectors like the BD45xx series. Consider the 0.85µA current consumption for low-power applications. Verify that the 5.9V detection threshold aligns with the system's power rail requirements.

Part Context

The BD5359G-TR belongs to the BD53xx series of free delay time setting CMOS voltage detector ICs. This series is designed for high accuracy and low current consumption. It complements the BD52xx series, which utilizes N-channel open drain outputs. Both series share similar package options and core detection technologies but differ in output stage architecture.

Replacement Considerations

The BD5250G-1 is listed as a replacement with the same pinout and package. Note differences in detection voltage (5.0V vs 5.9V) and output type (Open drain vs CMOS). Verify compatibility with existing circuit designs before substitution.
