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

IOpeak = 3.0 A maximum (t ≤ 100 ms: single shot, between OUT1 and OUT2) IODC = 1.0 A maximum VOsat = 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 VCCcan be regulated at 1.86 V by connecting the V

control pin (V

CONT

) to the reference voltage, V

REF

(1.36 V). Also, the VCCoutput voltage can be varied by inputting the CPU D/A output to V

CONT

. Either the IC itself or only the VCCregulator 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 VCCregulator. Support for both CMOS and n-channel open drain outputs from the CPU.

Wiring Notes

1. Connect both the P-GND and both the VSpins. Although both the P-GND and VSlines are connected internally, both must be connected to provide currents of 1 A or over, or to provide even lower saturation output. However, operation with only one of each of these pairs connected, or with through power supply wiring, is possible.

2. Since large currents flow in the VSand P-GND lines, these lines should be made thicker, and line impedance reducing capacitors should be inserted in the vicinity of the IC.

3. Since S-GND is the ground for the control system, rather than using the same wiring as the P-GND line, it is preferable to connect this pin to the CPU ground line.

4. If the CPU outputs are CMOS outputs, connect VDDto the CPU power supply line and if they are n-channel open drain outputs, connect VDDto the VBpin (battery). However, since VDDis the control input system power supply, it should not be set to the same impedance as the VSline.

Sample OUT3P/OUT3N Pin Applications

The OUT3P and OUT3N pins support –20 mA (typical) and 20 mA (typical) constant current drive, respectively. Constant current is supported when VB= VS= 2.0 V or higher. A 5 kΩ shunt resistor between the OUT3P pin and ground is included within the IC. Inversely, the OUT3N pin is an open collector pin, and there is no resistor inserted between this pin and the VSpin. A current limiting resistor (resistance maintaining transistor) may be inserted between the OUT3P and OUT3N pins and the external transistors. These pins can also be used for direct LED drive, battery check, or other power supply switching functions.
