LB1981V Product details

Description

Pin number Pin name STBY 3 Pin voltage VCC1 max 0.2V min 100kΩ 3 100kΩ Equivalent circuit VCC1 Pin function When this pin is at 0.7V or less or when it is open, only the FG/PG amplifier operates.In the motor drive state, the pin should be at 2V or higher.A10858 4 SEL CSLP VCC1 max 0.2V min VCC1 100kΩ 4 100kΩ CSLP pin charge/discharge current switching pin.Setting this pin to 2V or higher switches the triangular wave slope that determines soft switching.A10859 5
