Driver for Digital Still Camera
1-2ch Lens Drivers
for SLRs (Single-lens Reflex)
BD65499MUV
●General Description
The BD65499MUV motor driver provides built–in boost
converter and 1ch H-bridge FULL ON driver.
Integrated boost converter for high voltage and large
current H-bridge, especially designed for mobile system
piezoelectric element with a compact surface mount
package.
●Features
Low ON resistance DMOS output
DC/DC boost converter
Output switching speed changeability
(DC/DC converter: 4 step, H-bridge: 2 step)
Charge pump less as using Pch DMOS for high-side
output (H-bridge)
Control input terminal available with 1.8V
With built-in Under Voltage Locked Out protection,
Thermal Shut Down, and Over Current Protection
circuit
