DMOS Microstepping Driver with Translator

and Overcurrent Protection

A5984

PACKAGES:

DESCRIPTION (continued)

Internal synchronous rectification control circuitry is provided to

improve power dissipation during PWM operation. Internal circuit

protectionincludes:thermalshutdownwithhysteresis,undervoltage

lockout(UVLO),andcrossover-currentprotection.Specialpower-on

sequencing is not required.

24-contact QFN

with exposed thermal pad

4 mm × 4 mm × 0.75 mm

(ES package)

The A5984 is supplied in three surface mount packages: two QFN

packages, the 4 mm × 4 mm, 0.75 mm nominal overall height ES

package, and the 5 mm × 5 mm × 0.90 mm ET package. The LP

package is a 24-pin TSSOP. All three packages have exposed pads

32-contact QFN

with exposed thermal pad

5 mm × 5 mm × 0.90 mm

(ET package)

for enhanced thermal dissipation, and are lead (Pb) free (suffix –T),

with 100% matte-tin-plated leadframes.
