3. Descriptions of HSA51 Pulse Width Modulation Amplifier

HSA51 is a type of pulse width modulation amplifier. It can provide 5A continuous output current to the load;the whole bridge structure can work in a wide voltage range,all the high-end and low-end switching drive control circuit,PWM pulse width modulation circuit are integrated with the product. Complete input circuit drive and power amplification wide adjustable square wave signal by  external PID loop speed and position control systems can be completed. Input signal to realize ban  on  internal H bridge switching off.
The series of the products are made of thick film hybrid integrated process, metal sealed shell package. Product design and manufacturing to meet the MIL-STD and detailed specifications of the product requirements, the highest quality level of H-class.

7.1 Power supply bypass
HSA51 power supply should have plenty of bypass to ensure its correct operation, or it may be unstable, reduces efficiency and output maybe oscillations. The VS power supply should add a 1μF ceramic capacitor and parallel a low ESR value of bypass capacitor , the size of at least selected 10μf/ A .The VCC is the same need to parallel a 0.1 μF ceramic capacitor and a low ESR value of 6.8μF-10μF bypass capacitor . All bypass capacitors should be connected as close as possible to the corresponding power source.
