Description
9, 10, 11, 12
Metal slug
GND
Power Ground
1
GND
Analog ground
2
Output Status-
flag (SF)
Open drain output, active low.
Is set according to the truth table .
3,13
18, 19
Inputs IN1,IN2
DI1,DI2, COD
Voltage controlled inputs with hysteresis
8
COD
When not connected or connected to GND, a stored failure will be reset by change of
the voltage-level on DI1 or DI2.
When connected to Vcc, the disable pin DI1 and DI2 are inactive. A stored failure will
be reset by change of the voltage-level on IN1 or IN2 .
6, 7, 14, 15
OUT1 , OUT2
H-Bridge outputs with integrated free-wheeling diodes.
4, 5, 16
Vbat
The pins 4 and 5 are internally connected. These pins supply the left high side and the
analogue/logic part of the device.
The pin 16 supplies the right high side and the charge pump.
The pins 4, 5 and 16 should be connected together on the printed circuit board with
connections as short as possible.
Supervision and protection functions
a) Supply voltage supervision
The supply voltage is supervised . If it is below its specific threshold , the power stages
are switched in tristate and the status flag is switched low.
If the supply voltage is over the specific theshold again , the power stage switches inde-
pendently into normal operation, according to the input pins and the status flag is reset .
b) Thermal supervision
In case of over-temperature the power stages are switched in tristate independent of
the inputs signals and the status flag is switched low.
If the level changes from high to low on DI1 (IN1) or low to high on DI2 ( IN2 ), the out-
put stage switches on again if the temperature is below the specified limit .The status-
flag is reset to high level (Pinnames in brackets refer to coding pin=Vcc).
c)
Supervision of overcurrent
If overcurrent is detected the power stages are independent of the inputs signals
switched in tristate and the status flag is set .
If the level changes from high to low on DI1 ( IN1 ) or low to high on DI2 ( IN2 ) the out-
put stage switches on again and the status flag is reset to high level (Pinnames in
brackets refer to coding pin = Vcc).
The output stage switches into the mode defined by the inputs pins provided the tem-
perature is below the specified limits .
d) Current limiting
The maximum current which can flow under normal operating conditions is limited to
Imax = 6,5A +/- 20% .When the maximum current value is reached, the output stages
are switched tristate for a fixed time. According to the time constant the current
decreases until the next switch on occurs. See page 8 for schematics.
