Pin Description
Pin
Symbol
Function
1
GND
T6818: ground; reference potential; internal connection to pin 7, 8 and 14; cooling tab
T6828: additional connection to heat slug
2
OUT3
Half-bridge output 3; formed by internally connected power MOS high-side switch 3 and low-side switch 3
with internal reverse diodes; short circuit protection; overtemperature protection; diagnosis for short and
open load
3
VS
Power supply for output stages OUT1, OUT2 and OUT3, internal supply
4
CS
Chip select input; 5-V CMOS logic level input with internal pull up;
low = serial communication is enabled, high = disabled
5
DI
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
6
CLK
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)
Ground; see pin 1
7
GND
8
GND
Ground; see pin 1
9
DO
Serial data output; 5-V CMOS logic level tristate output for output (status) register data; sends 16-bit
status information to the microcontroller (LSB is transferred first); output will remain tristated unless
device is selected by CS = low, therefore, several ICs can operate on one data output line only.
10
INH
Inhibit input; 5-V logic input with internal pull down; low = standby,
high = normal operation
11
VCC
Logic supply voltage (5 V)
12
OUT2
Half-bridge output 2; see pin 2
13
OUT1
Half-bridge output 1; see pin 2
14
GND
Ground; see pin 1
