Pin Description Pin Symbol Function 1 OUT3S Used only for final testing, to be connected to OUT3F 2 OUT3F Half-bridge output 3; formed by internally connecting 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 3CS Chip select input; 5V CMOS logic level input with internal pull-up; low = serial communication is enabled, high = disabled 4DI 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 transferred first 5CLK Serial clock input; 5V CMOS logic level input with internal pull-down; controls serial data input interface and internal shift register (fmax = 2 MHz) 6 PWM PWM input; 5V CMOS logic level input with internal pull-down 7DO Serial data output; 5V CMOS logic-level tri-state output for output (status) register data; sends 16-bit status information to the microcontroller (LSB transferred first); output will remain tri-stated unless device is selected by CS = low; this allows several ICs to operate on only one data-output line 8 GND Ground 9 VCC Logic supply voltage (5V) 10 VS1 Power supply for output stages OUT1 and OUT2; internal supply 11 VS2 Power supply for output stages OUT2 and OUT3; internal supply 12 OUT2F Half-bridge output 2; formed by internally connected power MOS high-side switch 2 and low-side switch 2 with internal reverse diodes; short circuit protection; overtemperature protection; diagnosis for short and open load 13 OUT2S Used only for final testing, to be connected to OUT2F 14 PGND2 Power ground OUT2 15 OUT1F Half-bridge output 1; formed by internally connected power MOS high-side switch 1 and low-side switch 1 with internal reverse diodes; short circuit protection; overtemperature protection; diagnosis for short and open load 16 OUT1S Used only for final testing, to be connected to OUT1F 17 PGND1 Power ground OUT1 18 PGND3 Power ground OUT3 |
