DMOS Full-Bridge Motor Driver

A3949SLB SOIC

Designed for PWM (pulse width modulated) control of dc motors, the

A3949 is capable of peak output currents to ±2.8 A and operating volt-

ages to 36 V.

PHASE and ENABLE input terminals are provided for use in control-

ling the speed and direction of a dc motor with externally applied PWM

control signals. Internal synchronous rectiﬁcation control circuitry is

provided to reduce power dissipation during PWM operation.

The A3949 is supplied in a choice of two power packages, a 16-pin

plastic SOIC with a copper batwing tab (part number sufﬁx LB), and

a low proﬁle (1.1mm) 16-pin TSSOP (sufﬁx LP) with exposed power

tab. Both packages are available in a lead-free version (100% matte tin

leadframe).

¹Output current rating may be limited by duty cycle,

ambient temperature, and heat sinking. Under any set of

conditions, DO NOT exceed the speciﬁed I_OUTor T_J.

²Measured on a typical two-sided PCB with 2 in.²copper

ground plane.

^*Pb-based variants are being phased out of the product line. The variants cited

in this footnote are in production but have been determined to be LAST TIME

BUY. This classiﬁcation indicates that sale of this device is currently restricted

to existing customer applications. The variants should not be purchased for

new design applications because obsolescence in the near future is probable.

Samples are no longer available. Status change: October 31, 2006. Deadline

for receipt of LAST TIME BUY orders: April 27, 2007. These variants include:

A3949SLB, A3949SLBTR, A3949SLP, and A3949SLPTR.

³Measured on a JEDEC-standard "High-K" 4-layer PCB.
