Mingjiada Electronics Supply ADI ADM6710 Low-Level High Accuracy Microprocessor Supervisory Circuit

With multi-voltage rail systems becoming increasingly common, microprocessors, FPGAs and SoCs often require multiple power supplies—such as a 1.2V core voltage, 1.8V/2.5V I/O voltages and a 3.3V peripheral voltage—to operate stably simultaneously. Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of the [ADI] ADM6710 low-level, high-precision monitoring circuit. This device can simultaneously monitor three or four voltage lines, providing a compact power monitoring solution for multi-rail systems with its low-voltage, high-precision characteristics.

[ADI] ADM6710 — Low-voltage, high-precision, three/four-voltage microprocessor monitoring circuit
The ADM6710 is a low-level, high-precision monitoring circuit. This device can monitor up to four system power supplies.
The ADM6710 incorporates a variety of internal pre-set under-voltage threshold options for monitoring 1.8 V, 2.5 V, 3.0 V, 3.3 V and 5.0 V supply voltages. The ADM6710Q offers three adjustable thresholds for monitoring voltages as low as 0.62 V.
The ADM6710’s output remains active as long as IN1 or IN2 exceeds 1 V, whilst for the ADM6710Q, the output remains active as long as VCC exceeds 2 V.

Low Voltage, High Precision: Monitoring Accuracy Determines System Reliability
The core metric for monitoring ICs is threshold accuracy. Insufficient threshold accuracy can result in either false resets (where the system repeatedly resets despite normal voltage) or missed events (where the voltage has fallen outside the safe range but a reset is not triggered). The ADM6710 is positioned as a ‘low-voltage, high-precision’ monitoring circuit; its reset threshold accuracy meets the stringent requirements of low-voltage rail monitoring—on low-voltage rails such as 1.2V and 1.8V, the margin available for monitoring is inherently narrow, and only high-precision threshold settings can ensure reliable triggering whilst avoiding false triggering.

Key Features:
Precise monitoring of up to four power supply voltages
Five reset threshold options: 1.8 V to 5 V
Monitoring voltage as low as 0.62 V (1.5% accuracy)
Typical reset delay time of 200 ms
Open-drain reset output (10 μA internal pull-up)
Reset output stage: Low-level active output when IN1 = 1 V or IN2 = 1 V
Low power consumption (35 μA)
Supply glitch suppression
Operating temperature range: –40 °C to +85 °C
6-pin SOT-23 package

Furthermore, the ADM6710 supports low-voltage operation and can be directly integrated into modern low-voltage digital systems without the need for additional level conversion. The reset output offers push-pull or open-drain options (depending on the specific model), and the reset delay time can be adjusted via an external capacitor, allowing system designers to configure it flexibly according to the processor’s reset timing requirements.
