TPS3423 I/O DESCRIPTION
PIN NAME 8 PIN SOT-5X3 6 PIN SOT-5X3
PB1 1 1 I Push-button input 1, refer Section 7.3.1.1 for additional details.
GND 2 2 - Ground connection for IC.
VDD 3 3 I Supply connection, connect a 0.1µF capacitor near the pin for best performance.
INT2 4 O Interrupt output for push-button input 2, INT2 is open drain active low output which toggles from every short press and long press on push-button input 2 as described in Section 7.3.2.1
INT1 5 O Interrupt output for push-button input 1, INT1 is open drain active low output which toggles from every short press and long press on push-button input 1 as described in Section 7.3.2.1
RESET1/RESET1 6 4 O RESET output for push-button input 1. The response of RESET to short press and long press is described in Section 7.3.2.2.
RESET2/RESET2 7 5 O RESET output for push-button input 2. The response of RESET to short press and long press is described in Section 7.3.2.2.
PB2 8 6 I Push-button input 2, refer Section 7.3.1.1 for additional details.

TPS3424 I/O DESCRIPTION
PIN NAME 8 PIN SOT-5X3 6 PIN SOT-5X3
PB 1 1 I Push-button input, refer Section 7.3.1.1 for additional details.
GND 2 2 - Ground connection for IC.
VDD 3 3 I Supply connection, connect a 0.1µF capacitor near the pin for best performance.
SPT 4 Connect capacitor to program short press time as described in Section 7.3.1.1 for SPT Cap version.
LPT 5 O Connect capacitor to program long press time as described in Section 7.3.1.1 for LPT Cap version.
RESET/RESET 6 4 O RESET output for the device. The response of RESET to short press and long press is described in Section 7.3.2.2.
INT 7 5 O Interrupt output. INT is open drain active low output which toggles from every short press and long press on push-button input as described in Section 7.3.2.1
KILL 8 6 I Kill is feedback from the host. RESET can be de-asserted in the latched version by pulling KILL low. Connect this pin to VDD if not used. Please refer Section 7.3.1.3 for additional details.
