LV8549MC No.A2039-3/5 Block Diagram Pin function Pin No. Pin name Pin function Equivalent Circuit 1 VCC Power-supply voltage pin. VCC voltage is impressed. The permissible operation voltage is from 4.0 to 16.0(V). The capacitor is connected for stabilization for GND pin (6pin). 2 ENA Motor drive control input pin. It shifts from the stand-by state to a prescribed output operation corresponding to the state of the input when the ENA pin becomes a standby mode by L, the circuit current can be adjusted to 0, and it makes it to H. It is a digital input, and the range of L level input is 0 to 0.7(V) and the range of H level input are 1.8 to 5.5(V). PWM can be input. Pull-down resistance 100(k Ω) is built into in the terminal. 3 IN1 Motor drive control input pin. Driving control input pin of OUT1 (10pin) and OUT2 (9pin). PWM can be input. With built-in pull-down resistance. 5VREG 4 IN2 Motor drive control input pin. Driving control input pin of OUT3 (8pin) and OUT4 (7pin). PWM can be input. With built-in pull-down resistance. 5 NC 6 GND Ground pin. 7 OUT4 Driving output pin. The motor coil is connected between terminal OUT3 (8pin). VCC OUT1 (OUT3) OUT2 (OUT4) 8 OUT3 Driving output pin. The motor coil is connected between terminal OUT4 (7pin). 9 OUT2 Driving output pin. The motor coil is connected between terminal OUT1 (10pin). 10 OUT1 Driving output pin. The motor coil is connected between terminal OUT2 (9pin). LVS INPUT LOGIC H-side PRE L-side PRE H-side PRE L-side PRE VCC VCC OUT1 OUT2 M OUT3 OUT4 IN1 IN2 ENA TSD VREF GND |
