2.5
2.5.1
The high-side switches are protected against a short of the output to ground by an over
current shutdown. If a high-side switch is turned on and the current rises above the high-
side shutdown threshold
transistors are turned off and bit 4 the SPI diagnosis word is set. During the delay time,
the current is limited to
set until a status register reset (bit 7 of SPI control word) is received or a power-on reset
is performed.
2.5.2
Due to the chopper current regulation, the low-side switches are protected against a
short to the supply voltage. To detect the short, the first time the current limit is reached,
the off-command for the low-side switch is blanked out for 10 μs. If the current rises
above the low-side shutdown threshold
turned off and bit 5 in the SPI diagnosis word is set. The value of the shutdown threshold
depends on the current limit that is set via the SPI. The shutdown threshold is 1 A higher
than the current limit. The output stages stay off and the error bit set until a status register
reset (bit 7 of SPI control word) is received or a power-on reset is performed.
2.5.3
The short circuit protection circuits of the high- and low-side switches work
independently of each other. In most cases, a short across the load will be detected as
a short to
shutdown threshold
2.5.4
If the current through the low side transistor is lower than the reference current
ON-state (PWM = H), a timer is started. After a filter time
recognized and the status bit 3 is set. If the current exceeds the reference current
the open load timer is reset. If the H-bridge is switched to OFF-state (PWM = L) the timer
is stopped but not reset. The timer continues if the H-bridge is switched to ON-state
again. There is no reset of the open load timer if the direction is changed using the DIR
input in open load condition. The open load error bit is latched and can be reset by the
status register reset bit 7 of the SPI control word or a POR.
2.5.5
Temperature sensors are integrated in the power stages. The temperature monitoring
circuit compares the measured temperature to the prewarning, warning and shutdown
