TERMINAL FUNCTIONS (continued)
TERMINAL
I/O
DESCRIPTION
NO.
NAME
16
PWM_DP
I
Positive audio signal PWM input for channel D (Must be the complement of PWM_DN)
17
PWM_DN
–
Negative audio signal PWM input for channel D (Must be the complement of PWM_DP)
18
RESET
I
Enable/Disable pin
RESET = High, normal operation
RESET = Low, held in reset mode
19
FAULT
O
Short circuit fault
FAULT = High, normal operation
FAULT = Low, short circuit at output detected. FAULT will latch if short circuit detected and will be
reset if the RESET pin is pulled low or the VCC power supplies are turned off. Thermal fault will
not be reported by the FAULT pin.
20
SE/BTL
I
Single-ended or Bridge-tied output select terminal. If any output is configured as a single-ended
load, this pin should be connected to DVDD. For 2-channel, BTL operation, connect to GND.
21
THERM_WARN
O
Thermal warning output flag.
THERM_WARN = HIGH, normal operation.
THERM_WARN = LOW, die temperature has reached 125 deg. C. Automatically resets when
temperature falls back to normal range. TTL compatible push-pull output.
41
BYPASS
O
VCC/8 reference for analog cells
47
BSB
I/O
Bootstrap I/O for channel B high-side FET
46
VCLAMP_AB
–
Internally generated voltage supply for channel A and B bootstrap. Not to be used as a supply or
connected to any component other than the decoupling capacitor.
45
BSA
I/O
Bootstrap I/O for channel A high-side FET
4–6
PVCCA
–
