OUTPUT (L) Logic output, ACTIVE LOW. HMUTEB low indicates TPS4100A is in mute
OUTPUT (L) Open Drain Logic Output, ACTIVE HIGH. FAULT high indicates fault condition.
INPUT (L) Logic input, ACTIVE LOW. Setting SLEEP to low puts the TPS4100A in sleep
INPUT (L) Non-inverted switching modulator inputs.
INPUT (L) Inverted switching modulator inputs.
INPUT (L) Logic Input, ACTIVE LOW. Setting MUTE to low puts the device in mute mode.
INPUT (L) Logic input, ACTIVE HIGH. Enables Analog Mode operation. Typically driven
