TEXAS INSTRUMENTS TPS3895ADRYR

The TPS3895ADRYR is a single-channel ultra-small adjustable Supervisory Circuit with active-high push-pull 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 power-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 versions, 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.
