Table 2-1. Pin Description SO28
Pin Symbol Function
1, 2 OUT5
Half-bridge output 5; formed by internally connected power MOS high-side switch 5 and low-side switch 5
with internal reverse diodes; short circuit protection; overtemperature protection; diagnosis for short and
open load
3, 4 OUT4 Output 4; see pin 1
5 VS Power supply output stages HS4, HS5, HS6, internal supply; external connection to pin 10 necessary
6, 7, 8, 9 GND Ground; reference potential; internal connection to pins 20 to 23; cooling tab
10 VS Power supply output stages HS1, HS2 and HS3
11, 12 OUT3 Output 3; see pin 1
13, 14 OUT2 Output 2; see pin 1
15, 16 OUT1 Output 1; see pin 1
17 INH Inhibit input, 5V logic input with internal pull down, low = standby, high = normal operation
18 DO
Serial data output, 5V 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 one data output line only
19 VCC Logic supply voltage (5V)
20, 21,
22, 23
GND Ground, see pins 6 to 9
24 CS
Chip select input, 5V CMOS logic level input with internal pull up;
low = serial communication is enabled, high = disabled
25 CLK
Serial clock input, 5V CMOS logic level input with internal pull down,
controls serial data input interface and internal shift register (f
max
= 2MHz)
26 DI
Serial data input; 5V 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
27, 28 OUT6 Output 6; see pin 1
