VS
Power supply voltage (external reverse protection required)
For this input a ceramic capacitor as close as possible to GND is
recommended.
Important: for the capability of driving the full current at the outputs all
pins of VS must be externally connected.
8DI
Serial data input
The input requires CMOS logic levels and receives serial data from the
microcontroller. The data is an 24bit control word and the least
significant bit (LSB, bit 0) is transferred first.
9
CM/PWM2
Current monitor output/PWM2 input
Depending on the selected multiplexer bits of Input Data Register this
output sources an image of the instant current through the
corresponding highside driver with a ratio of 1/10.000. This pin is
bidirectional. The microcontroller can overdrive the current monitor
signal to provide a second PWM input for the output OUT7.
10
CSN
Chip select not input / test mode
This input is low active and requires CMOS logic levels. The serial data
transfer between L9953 and micro controller is enabled by pulling the
input CSN to low level. If an input voltage of more than 7.5V is applied
to CSN pin the L9953 will be switched into a test mode.
11
DO
Serial data output
The diagnosis data is available via the SPI and this tristate-output. The
output will remain in tristate, if the chip is not selected by the input CSN
(CSN = high)
12
VCC
Logic supply voltage
For this input a ceramic capacitor as close as possible to GND is
recommended.
13
CLK
Serial clock input
This input controls the internal shift register of the SPI and requires
CMOS logic levels.
16,17, 20,21,
OUT4
OUT5
Half-bridge-output 4,5: see OUT1 (pin 3).
Important: for the capability of driving the full current at the outputs both
pins of OUT4 (OUT5, respectively) must be externally connected.
26
CP
Charge pump output
This output is provided to drive the gate of an external n-channel power
MOS used for reverse polarity protection
27
PWM1
PWM1 input:
This input signal can be used to control the drivers OUT1-OUT6 and
OUT8 by an external PWM signal.
