Micrel, Inc. Dual Voltage Supervisor IC MIC2774L-46BM5

The MIC2774L-46BM5 is a dual power supply supervisor designed for under-voltage monitoring and power-on reset generation in a compact 5-pin SOT package. It features two independent under-voltage detectors: one with a fixed threshold and another that is user-adjustable, allowing for monitoring of voltages as low as 0.3V. The device provides a choice of active-low reset outputs and asserts these outputs during power-on and whenever monitored voltages drop below their respective thresholds, maintaining the assertion for a minimum of 140ms after recovery. With a typical supply current of only 3.5¬µA, the MIC2774L-46BM5 is suitable for low-power applications. It includes hysteresis to prevent false triggering from noise and can be used in various applications such as embedded controllers, telecommunications systems, and networking hardware. The operating temperature range is from -40¬8C to +85¬8C, making it versatile for different environments. The part number is part of a series that offers multiple factory-programmed voltage thresholds, enhancing its adaptability for different supply voltage requirements.
