Over-Voltage Protection
If voltage on the FB pin exceeds 115% of V REF for two
consecutive clock cycles, the fault latch is set and
shutdown occurs.
A shorted high-side MOSFET condition is detected
when SW voltage exceeds ~0.7 V while the low-side
MOSFET is fully enhanced. The fault latch is set
immediately upon detection.
The OV/UV fault protection circuits above are active all
the time, including during soft-start.
Over-Temperature Protection (OTP)
The chip incorporates an over-temperature protection
circuit that sets the fault latch when a die temperature of
about 150°C is reached. The IC restarts when the die
temperature falls below 125°C.
If auto-restart is not desired, tie the EN pin to the VCC
pin or pull it HIGH after V CC comes up with a logic gate
to keep the 1 μA current sink from discharging EN to
1.1V. Figure 32 shows one method to pull up EN to V CC
for a latch configuration.
Auto-Restart
After a fault, EN pin is discharged by a 1 μA current sink
Figure 32.
Enable Control with Latch Option
to a 1.1 V threshold before the internal 800 K Ω pull-up is
restored. A new soft-start cycle begins when EN
charges above 1.35 V.
Depending on the external circuit, the FAN2110 can be
configured to remain latched-off or to automatically
restart after a fault.
Table 1. Fault / Restart Configurations
Power-Good (PGOOD) Signal
PGOOD is an open-drain output that asserts LOW when
V OUT is out of regulation, as measured at the FB pin.
Thresholds are specified in the Electrical Specifications
section. PGOOD does not assert HIGH until the fault
latch is enabled (T1.0) (see Figure 31) .
