TPS3808G01DBVT, Монитор питания с программируемой задержкой и ручным сбросом

Описание TPS3808G01DBVT The TPS3808G01DBVT is a Low Quiescent Current Programmable Delay Supervisory Circuit that monitors system voltages from 0.4 to 5V, asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the user-adjustable delay time after the SENSE voltage and manual reset (MR) return above the respective thresholds. The TPS3808 device uses a precision reference to achieve 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 can be user-adjusted between 1.25ms and 10s by connecting the CT pin to an external capacitor. The TPS3808 device has a very low typical quiescent current of 2.4µA, so it is well-suited to battery-powered applications. • Power-on reset generator with adjustable delay time (1.25ms to 10s) • Very low quiescent current (2.4µA typical) • High threshold accuracy (0.5% typical) • Fixed threshold voltages for standard voltage rails from 0.9 to 5V & adjustable voltage down to 0.4V • Manual reset (MR) input • Open-drain reset output • Green product and no Sb/Br Типsimple reset/power-on resetКоличество проверяемых напряжений1Выходopen drain or open collectorСбросactive lowСброс ожидания, мс (Min)adjПороговое напряжение, ВadjРабочая температура, °C-40…+125Корпусsot-23-6Вес, г0.403
