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) |
