Pin Description

LB11823M

22

Equivalent circuit

Power pin (VCC3) for use during application with the supply

22

23

VCC3

12REG

voltage of 12 V or more. 12 V is generated at the 12 REG

pin. To use the 12REG pin, connect this pin to VCC1.

When not used, keep both VCC3 and 12 REG open or

23

connect them to GND.

VCC2

PWM waveform comparator pin.

24

TOC Normally used in the open condition. By inputting the

voltage directly into this pin, the output duty can be

controlled without using the VCTL amp.

24

20kΩ

VCC2

Pin to set the PWM oscillation frequency.

25

PWM

Connect a capacitor between this pin and GND.

200Ω

25

2kΩ

VCC2

34kΩ

Control voltage input pin.

26

VCTL

For control with this pin, set the PWMIN pin to the L level.

2.26V

40kΩ

26

Pin to set the operation time of motor lock protection circuit

and to set the initial reset pulse.

27

CSD Connect a capacitor between this pin and GND. When the

protection circuit is not to be used, connect a capacitor and

resistor (150kΩ, 4700pF) in parallel between this pin and

GND.

VREG

300Ω
