BD5236G-TR

Overview

The BD5236G-TR is a voltage detector from the ROHM BD52 series, designed for monitoring single-channel power supplies. It features an adjustable reset delay timer and an open-drain output active low. The device operates within a supply voltage range of 0.95 V to 10 V, with a typical under-voltage detection threshold of 3.6 V and ±1% precision. It includes hysteresis voltage defined as VDET x 0.05. The component supports surface mount installation in an SSOP-5 package and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Adjustable reset delay timer functionality
• Open-drain output configuration
• Single input voltage monitoring capability

Applications

• Portable equipment power management
• Microprocessor system supervision
• Battery-powered device protection

Procurement Notes

Verify the current supply status before procurement, as this part is marked Not Recommended for New Designs (NRND). Confirm that existing inventory meets project requirements since new design adoption is discouraged. Ensure compatibility with legacy designs rather than initiating new implementations. Check datasheet revisions for any specific handling or storage instructions relevant to the SSOP-5 package.

Selection Notes

Select this component only for maintaining existing designs where the BD5236G-TR is already integrated. Consider the BD5236G-1 as a recommended alternative for new projects due to similar pinout and package specifications. Evaluate if the adjustable delay feature is necessary, as fixed-delay alternatives exist within the portfolio. Verify that the 0.95 V minimum operating voltage aligns with the target application's power rail characteristics.

Part Context

This component belongs to the BD52 series of voltage detectors manufactured by ROHM Semiconductor. It is categorized under PMIC - Power Management ICs and specifically falls into the Supervisory Circuits subcategory. The part is distinct from other series like BD46 or BD48, which may offer different features such as manual reset or watchdog timers.

Replacement Considerations

The BD5236G-1 is listed as a recommended replacement with the same pinout and package. Other potential substitutes include BU4236G and BD5236FVE, though these may have different supply statuses or slight specification variations.
