LB8632V

Low-Voltage/Low-Saturation

Camera Motor Driver

Overview

The LB8632V is a general-purpose camera motor driver

IC that supports low-saturation output and low-voltage

drive and thus can be used in a wide range of applications.

The LB8632V is a miniature thin form-factor IC that

provides circuit structures and I/O logic that reduce

development times and costs and support reduced lot sizes

and end product diversity, despite increasing

miniaturization and functionality in application products.

Since the LB8632V supports low-voltage operation

(starting from 1.2 V) in addition to low-saturation outputs,

it provides characteristics that can withstand operation in

low-voltage ranges even in 3 V popularly-priced cameras

that do not include a step-up circuit. Since the LB8632V

supports IIL, control logic can be optimized by using two

ICs in parallel, thus allowing even more actuators to be

driven with a small number of CPU output ports. Thus the

LB8632V can also be used in 6 V top-of-the-line end

products.

Features

• 3, 6 V and a wide application range: from popularly

priced models to top-of-the-line products

The external transistors and the number of ICs (one or

two) is determined by the number of IC required motors

and actuators.

Support for motor standby, forward, reverse and braking

control for four motors using only five CPU port lines.

This requires two external transistors and two ICs. The

LB8632V also provides non-operating mode logic for

the operating control signals (the IN input) so that ICs

with other functions can be used on the same ports.

• Built-in 1 CH low-voltage drive low-saturation,

forward/reverse motor drive

IO peak = 3.0 A maximum (t ≤ 100 ms: single shot,

between OUT1 and OUT2)

IO DC = 1.0 A maximum

VO sat = 0.45 V typical (at IO = 1 A)

Operating voltage range: VB = 1.2 to 7.5 V (VB = VS =

VDD = battery voltage)

• Built-in low-voltage drive - 0.5 CH forward/reverse

motor driver

Supports 1.5 CH bridge operation with the use of two

external transistors. Also supports LED or solenoid

drive with constant-current drive.

Operating voltage range: VB = 1.2 to 7.5 V (VB = VS =

VDD = battery voltage)

• Built-in regulator predriver

VCC can be regulated at 1.86 V by connecting the VCC

control pin (VCONT) to the reference voltage, VREF

(1.36 V). Also, the VCC output voltage can be varied by

inputting the CPU D/A output to VCONT.

Either the IC itself or only the VCC regulator can be

turned on according to the operating mode of each

motor.

In addition, this function can also be used as a battery

check comparator.

Operating voltage range: VB = 1.5 to 7.5 V

• Three independent power supply line systems

The LB8632V supports either single supply

specifications (VB = VS = VDD) or dual supply

specifications (battery/step-up supply) by providing a

power supply voltage pin (VB), a motor supply pin (VS),

and a CPU interface pin (VDD). Also, motor output can

be stabilized by taking the motor power supply from the

VCC regulator.

Support for both CMOS and n-channel open drain

outputs from the CPU.
