Mingjiada Supply ADI ADM8316, ADM8320 And ADM8321 Series Supervisory Circuits

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the [ADI] ADM8316, ADM8320 and ADM8321 series of power supply monitoring circuits. These devices are designed for power supply monitoring and reset management in microprocessors, digital signal processors and embedded systems. They provide functions such as power-on reset, under-voltage monitoring and watchdog protection, and are suitable for applications including industrial control, communications equipment, automotive electronics and portable instruments.

The ADM8316, ADM8320 and ADM8321 belong to ADI’s power supply monitoring (Supervisory) product line. They are primarily used to monitor the system’s supply voltage and generate a reset signal in the event of an anomaly, thereby preventing microprocessors from malfunctioning during under-voltage conditions or during power-up/power-down sequences. Devices in this series typically feature precision voltage threshold monitoring, configurable reset timeouts, manual reset inputs and watchdog timers, helping designers enhance system reliability and immunity to interference. Their low-power characteristics and compact packaging also make them suitable for space- and power-sensitive embedded designs.
