SA60SA60 SA60 H-Bridge Motor Driver/Amplifiers FEATURES DESCRIPTION The SA60 is a pulse width modulation amplifier that LOW COST COMPLETE H-BRIDGE can supply 10A continuous current to the load. The full SELF-CONTAINED SMART LOWSIDE/ bridge amplifier can be operated over a wide range HIGHSIDE DRIVE CIRCUITRY of supply voltages. All of the drive/control circuitry for WIDE SUPPLY RANGE: UP TO 80V the lowside and highside switches are internal to the 10A CONTINUOUS OUTPUT hybrid. The PWM circuitry is internal as well, leaving ISOLATED CASE ALLOWS DIRECT the user to only provide an analog signal for the motor HEATSINKING speed/direction, or audio signal for switchmode audio FOUR QUADRANT OPERATION, TORQUE amplification. The internal PWM frequency can be pro- CONTROL CAPABILITY grammed by an external integrator capacitor. Alterna - INTERNAL/PROGRAMMABLE PWM tively, the user may provide an external TTL-compatible PWM signal for simultaneous amplitude and direction FREQUENCY GENERATION control for four quadrant mode.
