The MAX6700UT+T is a low voltage, high accuracy, triple voltage microprocessor supervisory circuit in 6 pin SOT-23 package. This precision triple voltage microprocessor (μP) supervisory circuits monitor up to triple system supply voltages and assert a single reset if any supply voltage drops below its preset threshold. This device significantly reduce system size and component count while improving reliability compared to separate ICs or discrete components. A single active-low output asserts when any monitored input falls below its associated threshold. The open-drain output has a weak internal pull-up (10μA) to IN2. The MAX6700 acts as a voltage detector with a propagation delay of 5μs after all monitored voltages exceed their thresholds.
- Supply voltage range is 2V to 5.5V
- Operating temperature range from -40°C to 85°C
- Low 35μA supply current
- Open drain RESET output with 10μA internal pull-up
- RESET valid to IN1 = 1V or IN2 = 1V
- Immune to short monitored supply transients
- Separate unmonitored power supply input (VCC) and three adjustable voltage monitored inputs
- Adjustable voltage threshold monitors down to 0.62V with 1.5% accuracy
