Test Procedure for the LV8075LPGEVB Evaluation Board OUTPUT Full-Drive (VCC-VC short) LV8075LP (50.0 mm × 50.0 mm × 1.6 mm, glass epoxy 1-layer board) base on VCT16 basic board. OUTPUT constant voltage 1.5V drive (VC voltage setting) 1/8/2014 1 www.onsemi.com Supply Voltage: • • • VCC (2.5 to 5.5V): Control voltage Supply for LSI VM (2.5 to 5.5V): Power Supply for LSI VC( 0 to VCC ):Constant voltage control setting Testing Procedure for DC Motor Control: 1. Motor Connection: Connect the Motor(s) between OUT1 and OUT2. 2. Power Supply: Supply DC voltage to VCC, VM. 3. Motor Operation: Set EN and IN1 and IN2 terminals according to the purpose (See LV8075LP datasheet).
