shorted LED happens to be in the LED string with the highest
forward voltage, the DHC circuit will automatically regulate
the output voltage with respect to the new highest LED
voltage. If more LEDs are shorted in the same LED string, it
may cause excessive power dissipation in the channel which
may cause the OTT circuit to trip which will completely
shutdown the device.
OVER-TEMPERATURE PROTECTION
measures die temperature. If the IC temperature exceeds the
OTT threshold, the IC will turn off all power sources inside the
IC (LED drivers, boost and internal regulators) until the

The 34844 has an on-chip temperature sensor that
temperature falls below the falling OTT threshold. Once it
comes back on, it will operate with the default configuration
