Monolithic Linear IC
LB11820M
Direct PWM Drive Brushless Pre-Driver for
Household Appliance Motors
Overview
The LB11820M is a direct PWM drive pre-driver IC that
is appropriate for 3-phase power brushless motors. This IC
can implement motor driver circuits that provide the
desired output capabilities (voltage and current) by the use
of appropriate discrete transistors in the output circuit. The
LB11820M is optimal for driving the large motors used in
air conditioners and on-demand hot water heaters.

Function
LB11820M
9 IN1+ Hall amplifier input.
10 IN1– IN+ > IN– is the input high state, and the reverse is
11 IN2+ the input low state.
12 IN2– Connect a capacitor between the sIN+ and IN–
13
IN3+
inputs if there is noise in the Hall sensor signals.
14 IN3–
15 VREG Regulated-voltage output pin (5V output)
Connect a capacitor (about 0.1 µF) between this pin
and ground for stabilization.
Equivalent circuit
16 VCC2 Power pin (PWM oscillation, PWM comparator,
VCTL amp). Normally connect to VREG.
17 LVS Voltage detection pin for low-voltage protection.
To detect the supply voltage of 5 V or more, connect
the zenor diode in series to set the detection voltage.
18 VCC3 Power pin (VCC3) for use during application with the
19 12REG supply 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 connect them to GND.
20 TOC PWM waveform comparator pin.
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.
