Pin function

Ground for all circuits other than the output circuits

All circuits stop when this pin falls below 0.4 V or is

open. In this state, the circuit current will be 10 µA

or lower. Set this pin to 2 V or higher to operate the

LB1882V in the motor drive state.

Motor forward/reverse switching

Low level: Forward (0 to 0.4 V)

High level: Reverse (1.6 V to VCC2)

W-phase Hall device input

The logic high level is the state

where WIN1 > WIN2.

V-phase Hall device input

The logic high level is the state

where VIN1 > VIN2.

U-phase Hall device input

The logic high level is the state

where UIN1 > UIN1.

Output transistor ground

Detecting the voltage on this pin is used to

implement fixed current drive and the current limiter

function.
