Over voltage Shutdown and Diagnostics
If the voltage at the BAT pin is above VBAT
set (SPI Message +11 bit OVL). During over voltage condition the integrator of the steady state current control is
halted (actual value of the duty cycle is not changed during over voltage). All other functions operate normally (e.g.
ADC, Dithering, Auto zero, Filters, …).
Electrical Characteristics:
V5D = 4.75V to 5.25V, Vbat = 5.5V to 42V,
current flowing into pin (unless otherwise specified)
