Mingjiada Supply Maxim MAX6463, MAX6464, MAX6746 And MAX6747 Microprocessor Supervisory Circuits

In embedded systems, industrial control, communication modules and portable devices, microprocessor (µP) monitoring circuits perform critical tasks such as power-on reset, under-voltage detection and protection against power supply anomalies. Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of the [Maxim] MAX6463/MAX6464 and MAX6746/MAX6747 series of microprocessor (µP) monitoring circuits, providing reliable power monitoring and reset solutions for µP systems.

I. 【Maxim】MAX6463 | MAX6464 — Ultra-low-power voltage detectors and microprocessor monitoring circuits
1. Description: The MAX6463/MAX6464 are a series of ultra-low-power voltage detectors and µP reset monitoring circuits, suitable for monitoring battery, supply and system voltages. Each device features a precise bandgap reference, a comparator, an internal resistor network for threshold setting, and a 5% threshold hysteresis circuit. The MAX6463 is a voltage detector with a propagation delay of 17 µs. The MAX6464 is a microprocessor monitoring circuit with a minimum reset delay of 150 ms; all devices provide thresholds ranging from +1.6 V to +5.5 V in 100 mV steps.
