DESCRIPTION

The SA51 is a pulse width modulation amplifier that can supply 5A continuous current to the load. The full bridge amplifier can be operated over a wide range of supply voltages. All of the drive/control circuitry for the lowside and highside switches are internal to the hybrid. The user provides a TTL compatible PWM signal for simultaneous amplitude and direction control in four quadrant mode. The internal circuitry will provide proper deadtime protection for each half bridge. All N-channel FETs mean the best efficiency for the size, both in terms of on-resistance and switching capability. For an idle/sleep mode or for fault protection, a TTL compatible disable pin is provided so as to shut down all four transistors. The SA51 is packaged in a space efficient isolated 8-pin TO-3 that can be directly connected to a heatsink.
