Selection Guide
Note the A3953SB (DIP) and
the A3953SLB (SOIC) are
electrically identical and share
a common terminal number
assignment.

Description (continued)
When a logic low is applied to the BRAKE input, the braking
function is enabled. This overrides ENABLE and PHASE to turn
off both source drivers and turn on both sink drivers. The brake
function can be used to dynamically brake brush DC motors.
The A3953 is supplied in a choice of two power packages; a
16-pin dual-in-line plastic package with copper heat-sink tabs,

Output current rating may be limited by duty cycle, ambient
temperature, and heat sinking. Under any set of conditions, do
not exceed the specifi ed current rating or a junction tempera-
ture of 150°C.
Range S
Fault conditions that produce excessive junction temperature
will activate the device’s thermal shutdown circuitry. These
conditions can be tolerated but should be avoided.

and a 16-pin plastic SOIC with copper heat-sink tabs. For both
package styles, the power tab is at ground potential and needs no
electrical isolation. Each package type is available in a lead (Pb)
free version (100% matte tin plated leadframe).
