thresholds. As soon as a threshold is reached, the according status bits are set in the
SPI diagnosis word (c.f.
Table 5
). If the overtemperature shutdown threshold is reached,
the output stages are turned off. The temperature monitoring messages and the over
temperature shutdown are latched and can be reset by the status register reset bit 7 of
the SPI control word or a POR.
2.5.6
Power Supply Fail
The power supply Voltage is monitored for over- and under voltage lockout:
Under Voltage Lockout
If the supply voltage
V
S
drops below the switch off voltage
V
UV OFF
, all output
transistors are switched off and the power supply fail bit (bit 7 of the SPI diagnosis
word) is set. If
V
S
rises again and reaches the switch on voltage
V
UV ON
, the power
stages are restarted. The error bit, however, is latched and has to be reset by the
status register reset bit 7 of the SPI control word.
Over Voltage Lockout
If the supply voltage
V
S
rises above the switch off voltage
V
OV OFF
, all output transistors
are switched off and the power supply fail bit (bit 7 of the SPI diagnosis word) is set.
If
V
S
falls again and reaches the switch on voltage
V
OV ON
, the power stages are
restarted. The error bit, however, is latched and has to be reset by the status register
reset bit 7 of the SPI control word.
The OVLO is only active if control bit 6 is H. If the bit is low, the OVLO is deactivated.
2.5.7
Error Flag
Bit 0 of the SPI diagnosis word is an OR of the status bits 1 to 7. It can be read out without
full SPI communication as described in
Figure 8
.
