Technical Specifications:
The IMP708JEPA operates with a supply voltage range typically between 2.5V and 5.5V. It features a precision voltage monitoring circuit that detects when the supply voltage drops below the preset threshold. The reset output is active-low, meaning it is asserted (pulled low) when the voltage is below the threshold. The reset output remains asserted for a specified reset timeout period after the voltage rises above the threshold, ensuring that the microprocessor has sufficient time to initialize properly. The device is available in various reset threshold voltages to accommodate different microprocessor requirements. The low supply current minimizes the impact on the overall system power consumption.
