LB11851M
No.A0673-4/6
1. Power supply (VCC and VM) and ground
The wiring is separated into the control IC side (VCC line) and the motor output side (VM line) by the diode DI, which
protects the IC from destruction on reverse connection. The application circuit uses 1
μ
F capacitors to prevent line
oscillation when kickback occurs. Similarly, 1
μ
F capacitors are also used on the VCC line for power supply line
stabilization.
2. PWMIN
The LB11851M accepts an open-drain output signal from the microcontroller with this pin and controls the on/off
states of the PMOS transistor (OUT1P and OUT2P) outputs accordingly. A constant-current bias is provided from
5VREG internally to the IC.
3. FGIN
The LB11851M accepts a CMOS output from the microcontroller with this pin and determines the drive phase output
(OUT1P, OUT2P, OUT1N, or OUT2N).
4. 5VREG
This is the power supply for the microcontroller, Hall effect sensors, and other circuits. A capacitor with a value of
1
μ
F is used for output stabilization. This pin has an output current capacity of 20mA.
5. SENSE
A sensing resistor is used for current detection. If the SENSE pin voltage exceeds 0.2V, the PMOS transistors are
turned off and only low side regeneration is performed.
