Internal Oscillator for Digital PWM Timing

Description

Designed for pulse width modulated (PWM) current control of

DC motors, the A3959 is 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 A3959 provides a choice of three power packages, a 24-pin

DIP with batwing tabs (package suffix ‘B’), a 24-lead SOIC

with four internally-fused pins (package suffix ‘LB’), and a

thin (<1.2 mm) 28-pin TSSOP with an exposed thermal pad

(suffix ‘LP’). In all cases, the power pins and tabs are at ground

potential and need no electrical isolation. Each package is lead

(Pb) free, with 100% matte tin leadframes.

Packages:

Package B, 24-pin DIP

with exposed tabs

Package LB, 24-pin SOIC

with internally fused pins

Package LP, 28-pin TSSOP

with exposed thermal pad
