Pin Description
Pin
Symbol
Function
1
GND
Ground; reference potential; internal connection to pin 10, 11, 13 and 20; cooling tab
2DI
Serial data input; 5-V CMOS logic level input with internal pull-down; receives serial data from the control
device, DI expects a 16-bit control word with LSB being transferred first
3CS
Chip-select input; 5-V CMOS logic level input with internal pull-up;
low = serial communication is enabled, high = disabled
4CLK
Serial clock input; 5-V CMOS logic level input with internal pull down;
controls serial data input interface and internal shift register (f
max = 2 MHz)
5
INH
Inhibit input; 5-V logic input with internal pull-down; low = standby, high = normal operating
6, 7
VS
Power supply output stages HS1, HS2 and HS3
8LS3
Low-side driver output 3; power-MOS open drain with internal reverse diode: overvoltage protection by
active zenering; short-circuit protection; diagnosis for short and open load
9
n.c.
Not connected
10
GND
Ground (see pin 1) be consistant
11
GND
Ground (see pin 1)
12
HS3
High-side driver output 3; power-MOS open drain with internal reverse diode: overvoltage protection by
active zenering; short-circuit protection; diagnosis for short and open load
13
GND
Ground (see pin 1)
14
HS2
High-side driver output 2 (see pin 12) be consistant
15
LS2
Low-side driver output 2 (see pin 8)
16
HS1
High-side driver output 1 (see pin 12)
17
LS1
Low-side driver output 1 (see pin 8)
18
DO
Serial data output; 5-V CMOS logic level tri-state output for output (status) register data; sends 16-bit
status information to the microcontroller (LSB is transferred first); output will remain tri-stated unless
device is selected by CS = low, therefore, several ICs can operate on only one data output line only.
19
VCC
Logic supply voltage (5V)
20
GND
Ground (see pin 1)
