When the voltage on the BAT pin exceeds the Overvoltage Shutdown Threshold (see
table below,
excessive power dissipation. A short filter with a typical value of 6.5 μs is included to
prevent undesired shutdown due to short transient voltage spikes. Although SPI
communication will remain functional, the output will remain off. The device will resume
normal operation when the BAT voltage has dropped below the overvoltage hysteresis
level. Note that the programmable registers are not reset, and the dither counter
continues to operate during an overvoltage event.
Both channels are disabled when an overvoltage condition is detected.
