BD52E30G-MTR

Overview

The BD52E30G-MTR is a voltage detector with an adjustable reset delay timer, designed for automotive applications and certified to AEC-Q100 standards. It features a typical under-voltage detection voltage of 3V with a precision of ±1%. The device supports a reset active voltage range from 0.95V to 10V and utilizes an open-drain output type with a low active state. It consumes 0.85µA in both ON and OFF states at VDET=4.8V. The hysteresis voltage is defined as VDET multiplied by 0.05. The L-output current capabilities are 0.4mA at low voltage and unspecified high voltage in the provided text, though other similar models indicate higher values. It operates within a temperature range of -40°C to 105°C and is housed in a 5-pin SSOP package.

Procurement Notes

Verify the specific revision and manufacturing date code upon order confirmation, as this component is marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing designs due to potential supply constraints. Confirm RoHS compliance status and packaging details directly with the supplier or manufacturer before finalizing procurement agreements.

Selection Notes

Select this component when an adjustable delay timer is required for automotive voltage supervision. Compare against the recommended replacement BD5230G-1 if new design implementation is necessary. Consider the open-drain output configuration and the specific 3V detection threshold relative to system requirements. Verify that the SSOP-5 package fits the available PCB footprint.

Part Context

This part belongs to the BD52E series of voltage detectors manufactured by Rohm Semiconductor. It is specifically engineered for automotive environments, adhering to strict reliability standards. The 'M' suffix typically denotes automotive qualification. It serves as a supervisory circuit to monitor power rails and trigger resets or alarms based on detected voltage levels.

Replacement Considerations

The BD5230G-1 is listed as a recommended replacement with the same pinout and package. Verify electrical parameter differences, such as circuit current consumption and reset active voltage range, before substituting.
