This device can function 4-channel- actuators by 1 chip due to include 4 channel BTL drivers. Three channels of this device, ch1, ch2 and ch3 can be controlled by PWM pulse. Two of them, ch1 and ch2 can also act in the Current Control mode. Furthermore, this device includes two mute circuits and TSD function. FEATURES q Low saturation voltage (at bootstrap). q (typical 0.7V at load current 500mA) q Wide supply voltage range. (4.5V to 13.2V) q Low cross-over distortion. q Two naked Operational Amplifiers q Divided Motor power supplies into three parts APPLICATION CD-ROM BLOCK DIAGRAM PIN CONFIGURATION (TOP VIEW) Outline 42P2R-D 42 39 40 41 1 4 3 2 38 5 37 6 34 9 33 10 32 11 31 12 13 14 30 29 7 8 36 35 15 28 16 27 17 26 18 25 19 20 24 23 21 22 OUT3 VM3(-) VM3(+) GND IN3- VREF0 IN3+ Vm3 VREF OP1+ OP2- VCC2 OP2+ IN4B- Vm2 OP1OUT OP1- IN4A- VM4(-) VM4(+) SOUT2 SIN2- GND IN2+ VM2(-) VM2(+) OUT2 IN2- VCC1 MUTE2 MUTE1 IN1- IN1+ OP2OUT SIN1- Vm1 SOUT1 VM1(-) OUT1 VM1(+) 24 25 27 28 29 30 31 34 35 36 37 38 39 40 MUTE1 TSD GND (4PIN) 1ch IN1+ + - - + CH3 + - + - - + CH4 + - + - - + CH2 + - + - - + CH1 + - VREF VREF0 4ch VCC1 MUTE2 + - + - + - + - IN1- OUT1 VM1(+) VM1(-) VM2(-) VM2(+) OUT2 IN2- IN2+ SIN1- SOUT1 SIN2- SOUT2 Vm1 VCC2 VM3(-) VM3(+) IN3+ IN3- OUT3 Vm3 VM4(-) VM4(+) IN4A- IN4B- Vm2 4 6 7 8 9 12 13 14 15 16 5 2 3 22 23 17 18 19 20 21 1 41 42 10 11 26 32 33 OP1+ OP1- OP1 OUT OP2+ OP2- OP2 OUT 2ch 3ch SLEEP Hi:Sleep VCC2 VCC1 VREF0 -- - OP1 OP2 A2 A4 A4 A3 A3 A3 A3 A3 A1 A1 A1 S1 E1 E2 S2 E3 E4 BIAS |
