SA160 SA160 SA160ASA160 H-Bridge Motor Driver/Amplifiers FEATURES LOW COST COMPLETE H-BRIDGE DESCRIPTION The SA160 is a pulse width modulation amplifier that SELF-CONTAINED SMART LOWSIDE/ can supply 10A continuous current to the load. The full HIGHSIDE DRIVE CIRCUITRY bridge amplifier can be operated over a wide range WIDE SUPPLY RANGE: UP TO 80V of supply voltages. All of the drive/control circuitry for 10A CONTINUOUS OUTPUT the lowside and highside switches are internal to the 14A CONTINUOUS OUTPUT FOR A-GRADE hybrid. The PWM circuitry is internal as well, leaving ISOLATED CASE ALLOWS DIRECT the user to only provide an analog signal for the mo- HEATSINKING tor speed/direc tion, or audio signal for switchmode FOUR QUADRANT OPERATION, TORQUE audio amplifica tion. The internal PWM frequency can CONTROL CAPABILITY be programmed by an external integrator capacitor. INTERNAL/PROGRAMMABLE PWM Alternatively, the user may provide an external TTL- compatible PWM signal for simultaneous amplitude FREQUENCY GENERATION and direction control for four quadrant mode.
