BD53E38G-TR

Overview

The BD53E38G-TR is a voltage detector IC from the BD52(53)ExxG series by ROHM Semiconductor. It features a typical under-voltage detection threshold of 3.8 V with ±1% precision. The device operates within a reset active voltage range of 0.95 to 10 V and supports an input supply voltage up to 10 V. It utilizes a CMOS output type with an adjustable delay timer and lacks manual reset or watchdog functions. The component is housed in an SSOP-5 package, operates between -40°C and +105°C, and consumes 0.85 μA in the ON state.

Feature Summary

• Features an adjustable delay timer for customizable reset timing.
• Provides high-precision voltage monitoring with ±1% accuracy.
• Utilizes a compact SSOP-5 surface-mount package.

Applications

• Portable electronic devices requiring low power consumption
• Battery-powered systems needing reliable voltage supervision
• General-purpose microcontroller reset circuits

Procurement Notes

Verify the NRND (Not Recommended for New Designs) status before procurement. Confirm that the SSOP-5 package and CMOS output specifications align with existing board layouts. Ensure the 3.8 V threshold meets system requirements as no alternative thresholds are available in this specific part number.

Selection Notes

Select this component when a fixed 3.8 V threshold with adjustable delay is required. Compare current consumption figures against other BD53 series variants if lower standby current is critical. Verify compatibility with the target operating temperature range of -40°C to +105°C for industrial or automotive environments.

Part Context

This part belongs to the BD52(53)ExxG family of voltage detectors. It shares pinout and functional similarities with the BD5238G-1 but differs in output type and precision specifications. The TR suffix indicates reel packaging for automated assembly processes.

Replacement Considerations

The BD5238G-1 is listed as a similar level replacement with the same pinout and package. Verify output type differences (Open Drain vs. CMOS) and precision variations before substitution.
