5.1
The device has incorporated a power-on reset circuit. This feature will reset the
commanded average current to 0 mA (device off), and will reset the programmable
registers to their default values. The fault register bits are reset during power on reset.
The device will remain off until a valid command is received. The device will also be reset
in the case of an undervoltage condition on the pin
pin REF pin is greater than the voltage on the pin
pin to the
