DALLAS, Sept. 22, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced the industry's first
auto focus voice coil driver with both pulse width modulation (PWM)
and linear current regulation support. The DRV201 provides
designers the flexibility to select the PWM or linear regulation
for compact cameras, smartphones and mobile devices. PWM current
regulation is up to 75-percent more power-efficient than
traditional designs using linear mode. The DRV201 is housed in TI's
PicoStar™ packaging, which is the industry's thinnest package at
0.15 mm, enabling low-profile camera modules. DRV201 also
integrates advanced ringing compensation in the silicon, to allow
faster lens stabilization and to work well with a wider selection
of lens and voice coil motor actuator suppliers. For samples and
evaluation modules, visit www.ti.com/drv201-pr.

The auto focus function is generally the most power-hungry and
battery-draining aspect of using the camera in smartphones and
other mobile devices. By designing in PWM mode, the DRV201 reduces
the power consumption of the auto focus function by 75 percent,
which helps extend the battery life of devices that include a
compact camera module.
Key features and benefits of the DRV201
- Flexible selection of operation mode with I2C
configuration.
- Advanced ringing compensation feature results in fast lens
settling time for faster focus – 10-mS settling time compared to
150 mS without ringing compensation.
- Robust on-chip protection (open and short-circuit
detection/protection, thermal protection and under-voltage
lockout).
- 0.15-mm package height.
Tools and support
TI offers a variety of tools and support to speed the
implementation of the DRV201 device:

- DRV201 IBIS model: www.ti.com/drv201-ibis-pr.
Availability and pricing
The DRV201 is available now in a 0.8-mm x 1.48-mm PicoStar
package, priced at $0.95 in
quantities of 1,000.
