BH6150F-E2

Overview

The BH6150F-E2 is a system reset IC manufactured by ROHM Semiconductor, designed to monitor power supply integrity for digital logic systems. It integrates two distinct reset circuits: an input voltage detector with a typical detection threshold of 1.25V and a transmission delay of 200µs, and a supply voltage detector with a typical detection level of 4.2V. The supply voltage detector offers selectable transmission delays of 25, 50, 100, or 200 ms, configurable via external Ct0 and Ct1 pins. Both circuits feature open-collector outputs and include internal 10kΩ pull-up resistors. The device supports a manual reset function and operates within an ambient temperature range of -20°C to +75°C, with a maximum power supply voltage rating of 45V.

Feature Summary

• Dual reset circuit architecture providing independent monitoring of input and supply voltages
• Configurable transmission delay for the supply voltage detector using external timing pins
• Integrated manual reset functionality for system control flexibility
• Built-in open-collector outputs with integrated 10kΩ pull-up resistors

Applications

• CPU system reset management
• MPU initialization control
• Logic circuit supervision

Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm package type and availability status. Ensure the Ct0 and Ct1 pin configuration matches the required delay selection for your design. Confirm RoHS compliance and operating temperature range requirements align with your application environment before finalizing procurement.

Selection Notes

Select this component when dual-channel reset monitoring is required for both input and supply rails. The configurable delay options allow optimization for different startup sequences. Verify that the 45V absolute maximum rating exceeds your system's peak voltage. Consider the open-collector output requirement for interfacing with downstream logic levels.

Part Context

The BH6150F belongs to ROHM's System Reset IC family, which provides reliable power-on reset signals for microprocessor and logic systems. This series is characterized by high integration, including built-in pull-up resistors and multiple delay options, reducing external component count. The BH6150F specifically addresses applications requiring simultaneous monitoring of separate voltage domains.
