Mingjiada Supply Maxim MAX6756 And MAX6759 Low-Power Single/Dual-Voltage Window Detectors

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the MAX6756/MAX6759 series of low-power, single/dual-voltage window detectors from Maxim (now part of ADI). This series of devices is designed for low-power electronic systems requiring simultaneous monitoring of overvoltage and undervoltage anomalies. They perform window comparisons on single or dual power supplies across a wide voltage range, providing a more comprehensive power monitoring solution for microprocessors, logic circuits and battery-powered equipment.

Window Detection: From ‘Undervoltage Reset’ to ‘Bidirectional Over- and Undervoltage Monitoring’
Traditional microprocessor monitoring circuits typically focus on undervoltage reset, generating a reset signal when the supply voltage falls below a threshold. However, in battery-powered, adapter-powered and multi-supply systems, excessively high voltages can similarly damage downstream components or cause system malfunctions. The MAX6756/MAX6759 series window detectors monitor whether the system voltage remains within a set upper and lower limit window; when the voltage exceeds this range, they output an alarm or reset signal, thereby providing bidirectional protection against both overvoltage and undervoltage.

Key Features:
Single or dual supply voltage monitors
Selectable factory-preset window thresholds for monitoring 5V, 3.3V, 3V, 2.5V, 1.8V, 1.5V, 1.2V and 0.9V supplies
Selectable externally adjustable window monitoring, providing supply monitoring down to 0.5V
Selectable window thresholds (±5%, ±10%, ±15%)
Single (combined UV/OV) or dual (independent UV and OV) outputs
Selectable timeout periods of 20 µs (typical) or 100 ms (minimum)
Manual reset input
Latch-type overvoltage output function
Immune to voltage transients
Low supply current of 10 µA
Low-voltage operation (output remains valid at VCC as low as 1 V)
Operating temperature range: –40 °C to +125 °C
Compact SOT23 and TDFN packages
