Off-State Diagnostics Timing Diagram - short to ground
Over voltage Shutdown and Diagnostics
If the voltage at the BAT pin is above VBATOV, the output drivers set all OUTx pins to low, and a diagnostic bit is
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,
T
j = -40 °C to +150 °C, all voltages with respect to ground, positive
current flowing into pin (unless otherwise specified)
