Description
describe The TPS3808 series microprocessor supervisory circuit monitors the system voltage from 0.4V to 5V and asserts the open-drain RESET signal when the SENSE voltage drops below a preset threshold or the manual reset (MR) pin falls to a logic low level. efficient. When the SENSE voltage and manual reset (MR) return values exceed their respective thresholds, the RESET output will remain low for a user-adjustable delay time. The TPS3808 device uses a precision voltage reference that achieves 0.5% threshold accuracy for VIT ≤3.3V. The reset delay time can be set to 20ms by disconnecting the CT pin, 300ms by connecting the CT pin to VDD using a resistor, or by connecting the CT pin to an external capacitor, the user can Adjust the reset delay time between 1.25ms and 10s. The TPS3808 device has an ultra-low typical quiescent current of 2.4 µA, making it ideal for battery-powered applications. It is available in SOT-23 and 2mm × 2mm WSON packages and is specified to operate from –40°C to 125°C (TJ).
