3 / 16 page  SDIP42 N o PLCC44 N o Name Functions 42 1 S1,2C Full bridge common source output to separate between power GND and logic GND. 1,41 2,44 OUT 1C, OUT 2C Output of the channel C bridge. 2 3 COM 1,2A High side DMOS channel A for current chopping in the windings connected pins to OUT 1A, OUT 2A. 3,39 4,42 Vp Power Supply Voltage. 4 5 COM 3,4A High side DMOS channel A for current chopping in the windings connected to pins OUT 3A, OUT 4A. 6,37 6,7,39,40 GND PowerGround and heatsink pins. 7,9, 11,14 8,10 12,14 OUT 1A, OUT 2A OUT 3A, OUT 4A Low side DMOS outputs of channel A stepper motor driver. 8 9 S1,2A Channel A sources of the DMOS OUT 1A, OUT 2A. A sensing resistor has to be connected from this pin and ground, for current control of phase 1,2 A. 10,33 11,35 CLAMP A, CLAMP B These pins have to be connected to an external zener diode to clamp the output voltage spikes of channel A/B. 12 13 S3,4A Channel A sources of the DMOS OUT 3A, OUT 4A. A sensing resistor has to be connected from this pin and ground, for current control of phase 3,4 A. 14 15 BOOT 1 A capacitor between this pin and Vp stores the overvoltage for each high side DMOS driver gate. 15 16 BOOT 3 A capacitor between this pin and internal diodes allows the change pump to transfer energy to the capacitor at the pin BOOT 1. 16,27 17,29 GND Logic Ground and Heatsink pins. 18 18 BOOT 2 Charge pump oscillator output. 19 19 SID Serial data input. 20 20 SCK Serial clock for serial data input. 21 21 STB Strobe to transfer the 16 bit shift register contents to the latch registers. 5,17 22,24 NC Not connected. 22,39 23 Vs Logic Supply Voltage. 23,24 25,26 A0TH / A1TH Open collector outputs for thermal informations to the µP. 25 27 OSC/ RESET An RC network connected to this pin defines the oscillator frequency for stepper drivers. When OSC/RES is <1V, a reset signal is internally generated. 26 28 V2 A voltage to this pin defines the output duty cycle of Channel C. 28 30 Cosc A capacitor connected to this pin defines the chopping frequency of channel C. 29 31 Vlow This pin is low when the chopping low voltage (V2 low level) is selected; it is in high impedance when the chopping high voltage (V2 high level) is selected. Only for CHC operation. 30,32, 34,36 32,34 36,38 OUT4B, OUT3B OUT2B ,OUT1B Low side DMOS outputs of channel B stepper motor driver. 31 33 S 3, 4B Same as S 3, 4A, but for channel B. 35 37 S 1, 2B Same as S 1, 2A, but for channel B. 38 41 COM 3, 4B Same as COM 3, 4A, but for channel B. 40 43 COM 1, 2B Same as COM 1, 2A, but for channel B.
