Designed for pulse-width modulated (PWM) current control of dc
motors, the A3959SB, A3959SLB, and A3959SLP are capable of
output currents to ±3 A and operating voltages to 50 V. Internal fixed
off-time PWM current-control timing circuitry can be adjusted via
control inputs to operate in slow, fast, and mixed current-decay modes.
PHASE and ENABLE input terminals are provided for use in
controlling 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.
Internal circuit protection includes thermal shutdown with
hysteresis, undervoltage monitoring of supply and charge pump, and
crossover-current protection. Special power-up sequencing is not
required.
The A3959SB/SLB/SLP is a choice of three power packages, a
24-pin plastic DIP with a copper batwing tab (package suffix ‘B’), a
24-lead plastic SOIC with a copper batwing tab (package suffix ‘LB’),
and a thin (<1.2 mm) 28-lead plastic TSSOP with an exposed thermal
pad (suffix ‘LP’). In all cases, the power tab is at ground potential and
needs no electrical isolation.
Each package is available in a lead-
free version (100% matte tin leadframe).

Output current rating may be limited by duty cycle,
ambient temperature, and heat sinking. Under any
set of conditions, do not exceed the specified
current rating or a junction temperature of 150°C.
Note that the A3959SLB(SOIC), A3959SB (DIP),
and A3959SLP (TSSOP) do not share a common
terminal assignment.
