TPS3897ADRYT

Схема контроля напряжения, выход сброса с активным высоким, 1.7В-6.5В (Vin), uSON-6.

The TPS3897ADRYT is a single-channel ultra-small adjustable Supervisory Circuit with active-high open-drain output. The very small supervisory circuit that monitor voltages greater than 500mV with a 0.25% (typical) threshold accuracy and offer adjustable delay time using external capacitors. The TPS389x family also has a logic enable pin (ENABLE or ENABLE) to power on and off the output. With the TPS3895, for example, when the input voltage pin (SENSE) rises above the threshold and the ENABLE pin is high, then the output pin (SENSE_OUT) goes high after the capacitor-adjustable delay time. When SENSE falls below the threshold or ENABLE is low, then SENSE_OUT goes low. For TPS389xA version, both SENSE and ENABLE have a capacitor-adjustable delay. The output asserts after this capacitor-adjustable delay when both SENSE and ENABLE inputs are good.
