Connect the test setup as shown above. 2. Set it according to the following guide. [Supply Voltage] VM (2.0 to 10.5V) : Power Supply for LSI VCC (2.7 to 5.5V) :Control Supply for LSI VIN (0 to VCC) : Logic “High” voltage for toggle switch [Toggle Switch State] Upper Side: High (VIN) Middle: Open, enable to external logic input Lower Side: Low (GND) [Operation Guide] 1. Initial Condition Setting: Set “Open” the toggle switches ENA, IN1 and IN2. 2. Power Supply: Supply DC voltage to VM, VCC and VIN. 3. Ready for Operation from Standby State: Turn “High” the ENA terminal toggle switch. 4. Motor Operation: Input the signal which is in condition to want to operate into IN1 and IN2. 3. Check the IN2, OUT1, and OUT2 terminal voltage at scope CH1, CH2, and CH3, and the output current waveform at scope CH4. Table2: Desired Results INPUT OUTPUT VM=6V * Refer to the following VCC=3V waveform VIN=3V ENA=High IN1=High IN2=10KHz (Duty50%) 1/8/2014 3 www.onsemi.com T=20µs/div IOUT (200mA/div) OUT2 (5Vdiv) OUT1 (5Vdiv) IN2 (5V/div) DCM output control logic ENA H L 1/8/2014 IN1 IN2 OUT1 OUT2 MODE H H L L Brake H L H L Forward L H L H Reverse L L Z Z Standby - - Z Z Standby 4 www.onsemi.com
