MAX6389XS29D3+T

The MAX6389XS29D3+T is a dual low voltage, low power microprocessor (μP) reset circuit in 4 pin SC-70 package. This microprocessor (μP) supervisory circuit monitors power supply voltage ranging from +1.8V to +5V while consuming only 3μA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. It has an open-drain active-low reset output. It has an auxiliary input for monitoring a second voltage. Typical application includes controllers, intelligent instruments, critical microprocessor (μP) and microcontroller (μC) power monitoring and battery powered equipment.

• Supply voltage range is 1V to 5.5V
• Operating temperature range from -40°C to 125°C
• Reset threshold voltage is 2.93V
• Reset threshold accuracy is ±2.5%
• Reset timeout delay is 280ms
• Reset output state is valid to VCC = 1V
• Negative going VCC transient immunity
• Low power consumption of 6μA at +3.6V
