7. Typical Connection Diagram of HSA01 High Reliaility Pulse Width Modulation Amplifier

HSA01 built-in error amplifier can provide gain for brush motor control in applications such as speed ring the typical connection is shown in figure 4.

Typical Connection Diagram
Figure 4  HSA01 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 oscillaged. Vs power supply should be connected with at least 1μF ceramic capacitor in parallel with  a low ESR value of the bypass capacitor, the capacitance should be  at least  10μf/A; All bypass capacitors should be connected as close as possible to the corresponding power supply root.

7.2 Unprotected circuit is a typical connection diagram
If the system does not require current limiting protection circuit, then the pin 8 can be directly grounded, as shown in Figure 5.
