Data Sheet
1.5
Figure 2 shows a block schematic diagram of the module. There are 3 halfbridge drivers
on the right-hand side. An HS driver and an LS driver are combined to form a halfbridge
driver in each case. The drivers communicate via the internal data bus with the logic and
the other control and monitoring functions: undervoltage (UV), overvoltage (OV),
overtemperature (TSD), charge pump and fault detect.
Two connection interfaces are provided for supply to the module: All power drivers are
connected to the supply voltage
undervoltage comparators with hysteresis, so that the correct function can be checked
in the application at any time.
The logic is supplied by the
generated Power-On Reset (POR) to initialize the module at power-on. The advantage
of this system is that information stored in the logic remains intact in the event of short-
term failures in the supply voltage

information is stored, and can be read out via the interface. The same logically applies
for overvoltage. “Interference spikes” on

high-impedance status (tristate). The module is initialized by

Protocol
The DO data output of one device is connected with the DI data input of the second
device. In this configuration these two devices are controlled with a single CSN chip
select and using a 32-bit wide control word.
The transmission cycle begins when the chip is selected with the CSN input (H to L). If
the CSN input changes from L to H then the word which has been read in becomes the
control word. The DO output switches to tristate status at this point, thereby releasing the
DO bus circuit for other uses.
The INH inhibit input can be used to cut off the complete module. This reduces the
current consumption to just a few A, and results in the loss of any data stored. The
output levels are switched to tristate status. The module is reinitialized with the internally
generated POR (Power-On Reset) at restart.
This feature allows the use of this module in battery-operated applications (vehicle body
control applications).
