Pin definitions and functions
Pin

Function
1, 18, 19,
36
GND
Ground
.
Reference potential.
Note: For the capability of driving the full current at the outputs all pins of
GND must be externally connected.
6, 7, 14,
15, 23, 24,
29, 32
VS
Power supply voltage (external reverse protection required).
For EMI reason a ceramic capacitor as close as possible to GND is
recommended.
Note: for the capability of driving the full current at the outputs all pins of
VS must be externally connected.
3, 4, 34
OUT1
Half-bridge output 1.
The output is built by a high side and a low side switch, which are
internally connected. The output stage of both switches is a power
DMOS transistor. Each driver has an internal reverse diode (bulk-drain-
diode: high side driver from output to VS, low side driver from GND to
output). This output is over-current and open-load protected.
Note: for the capability of driving the full current at the outputs all pins of
OUT1 must be externally connected.
8DI
Serial data input.
The input requires CMOS logic levels and receives serial data from the
microcontroller. The data is a 16bit control word and the least significant
bit (LSB, bit 0) is transferred first.
9CM/PWM
Current monitor output/PWM input.
Depending on the selected multiplexer bits (bit 9, 10, 11) of Input Data
Register this output sources an image of the instant current through the
corresponding high side driver with a ratio of 1/10.000. This pin is
bidirectional. The microcontroller can overwrite the current monitor signal
to provide a PWM input for all outputs.
Testmode:
If CSN is raised above 7.5V the device will enter the test mode. In test
mode this output can be used to measure some internal signals (see
10
CSN
Chip select not input / Testmode
.
This input is low active and requires CMOS logic levels. The serial data
transfer between L9951 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 L9951 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.
