PIN
NUMBER
20
NAME
OVSEL0
ACTION
Open (or Disconnected)
Short to Pin 21
EFFECT
The pin defaults to low due to the internal pulldown (see Note 8). The effect
depends on the intended overvoltage setting.
? If pin 20 and pin 21 have the same intended value, there is no effect for the
short.
? If pin 20 and pin 21 have a different setting, the V AA is shorted to AGND.
ALRM L goes low.
Open (or Disconnected)
The pin defaults to low due to the internal pulldown (see Note 8). The effect
depends on the intended overvoltage setting.

? If pin 21 and pin 22 have the same intended value, there is no effect for the
short.
? If pin 21 and pin 22 have a different setting, the V AA is shorted to AGND.
ALRM L goes low.
The pin defaults to low due to the internal pulldown (see Note 8). The effect
depends on the intended overvoltage setting.
? If pin 22 and pin 23 have the same intended value, there is no effect for the
short.
? If pin 22 and pin 23 have a different setting, the V AA is shorted to AGND.
ALRM L goes low.
The pin defaults to low due to the internal pulldown (see Note 8). The effect
depends on the intended overvoltage setting.

? If pin 23 is set high, there is no effect for the short.
? If pin 23 is set low, the V AA is shorted to AGND. ALRM L goes low.
ALRM L goes high.
ALRM L goes low.
V AA goes to approximately 100mV and ALRM L is approximately 0.5V. There is
no heartbeat if there is a one before the opening.
The device is in shutdown mode. ALRM L is low.
The pin is internally pulled down and the device goes to the shutdown mode.
ALRM L is low.
ALRM L goes high and stays high even if the short is removed. The internal
detect circuit considers this a major failure and the part has to be repowered
up to come out of this state.
Open (or Disconnected)
The signal at the ALRM L cannot be seen by the host.
27
ALRM L
Short to Pin 28
ALRM L goes high and stays high even if the short is removed. The internal
detect circuit considers this a major failure and the part has to be repowered
up to come out of this state.
Open (or Disconnected)
The delay between the fault condition and alarm setting (ALRM L goes high)
goes to the minimum. This means there is almost no delay.
28
CD
Short to Pin 29
The delay between the fault condition and alarm setting (ALRM L goes high) is
approximately 4s, which is set by the internal watchdog.
