3. Descriptions of HISA01 Isolated Pulse Width Modulation Amplifier

HISA01 isolated pulse width modulation amplifier works in switching mode, it can provide 300W of transmission power for the load; Products need two power supplies +5V for small control circuit power supply; 30V motor power supplies power to the internal H Bridge. There are two input control signals one is TTL level wide square wave input signal; the other is the DIR direction input signal that controls the direction of rotation of the power. The signal input is isolated from th-e power output
The product is made of thick film hybrid integrated process, metal sealed shell package. Product design and manufacturing  meet the MIL-STD and detailed specifications of the product requirements, the quality level is H-class.

HISA01 built-in error amplifier can provide gain for brush motor control in applications such as speed ring, the typical connection is shown as below figure

Typical Connection Diagram
Fig 4  HISA01 Typical connection Diagram

7.1 Power supply bypass:
Power supply VS should have sufficient bypass capacitors to ensure proper operation, otherwise it may be unstable and reduce efficiency, and the output may be oscillated. Vs power supply should connect with a 1MF at least ceramic capacitor paralleled with a low ESR value bypass capacitor. The capacitance should be at least 10μF/A. for VCC also requires a 0.1μF~0.47μFceramic capacitor and a low ESR value of 6.8μF~10μF parallel bypass capacitor, All bypass capacitors should be connected as close as possible to the corresponding power supply root.

7.2 The signal input is isolated from the power output
Input PWM(Pulse Width Modulation) square wave signal ground and DIR direction control signal ground and small signal power supply Vcc power ground should be common connected. Separate form the GND of the Vs to ensure that the signal input is isolated from the power output and that the output is stable and reliable.

7.3 DIR direction control signal input
DIR direction control signal is TTL level signal,to control the direction of the current between the OutA and OutB of the output,thereby controlling the direction of rotation of the motor. The working status of the motor is shown in the form below.
