JAJSGG5D November 2018 – March 2021 TPS3703-Q1
PRODUCTION DATA
The TPS3703-Q1 features a voltage latch mode on the RESET pin when connecting the CT pin to common ground . A pull-down resistor is recommended to limit current consumption of the system. In latch mode, if the RESET pin is low or triggers low, the pin will stay low regardless if VSENSE is within the acceptable voltage boundaries (VIT–(UV) < VSENSE < VIT+(OV)). To unlatch the device provide a voltage to the CT pin that is greater than the CT pin comparator threshold voltage, VCT. The RESET pin will trigger high instantaneously without any reset delay. A voltage greater than 1.2 V to recommended to ensure a proper unlatch. Use a series resistance to limit current when an unlatch voltage is applied. For more information, Section 9.2.2 gives an example of a typical latch application.
