7.3.2 Outputs

This section discusses the outputs of the TPS3423/4 devices.

7.3.2.1 Interrupt (INT)

INT is open drain active low output. This pin generates low pulse for short press and long press as shown in

Figure 6-1. Pulse duration for short press tINTS and long press tINTL is factory programmed. Please refer Section

4 section for the available option for the interrupt duration.

RESET is asserted for short press and de-asserted for long press on PB pin for latched version as shown

in Figure 6-1. Pulling KILL pin low also de-asserts the RESET in latched version as described in Figure 6-4.

Non-latched RESET helps in achieving complex logic function with push-button. Non-latched RESET version of

device supports multiple pattern as described in Section 4. RESET pattern is always different for short press and

long press. One of the non-latched RESET pattern is shown in Figure 6-3.
