8.3 Feature Description

A broad range of voltage threshold and hysteresis options are available for the TPS3842, allowing this device to be used in a wide array of applications. Reset threshold voltages can be factory-set from adjustable 0.7V or fixed from 2.7V to 9.5V. The adjustable variant can be set to any voltage above 0.7V using an external resistor divider. Connecting a capacitor between CTR and GND allows the designer to select any reset delay period up to 10s. Connecting a capacitor between CTS and GND allows the designer to select any sense delay period up to 10s.
