Layer

Description

S_ON_OFF

Bottom

The S_ON_OFF switch ensures that only one voltage source is driving the internal
power buses. The common pin (Pin 2) of the switch is directly connected to the input
of the TPS61029. V_BATT position selects an installed battery as the voltage source
for the board functions. The AUX_VDD position selects the source attached to the
AUX_VDD terminal as the voltage source for the board functions.

MODE_SW

Bottom

TIMER position (VDD) selects the TIMER mode of operation for the TPL5111. The
ONE_SHOT position (GND) selects the ONE SHOT mode of operation for the
TPL5111.

DONE

Top

SPST switch. Generates a DONE pulse when pressed.

M_DRV

Top

SPST switch. When pressed, connects VDD to the DELAY/M_DRV pin to simulate a
manual Power ON input to the TPL5111.
