3.4 Regulation Timer

In the following tests, SENSE3 is tied to GND to prevent reaching the VON3 threshold before the Regulation Timer expires. Sequence DOWN is initiated automatically by the device when REG_TMR expires. This time is set by the jumper and resistor used on the REG_TMR pin. If REG_TMR is floating, the Regulation Timer does not expire, and the device waits indefinitely for a condition that changes the state.
