A3955SB Frequently Asked Questions (FAQs)
The A3955SB can operate from -40°C to 150°C, but the recommended operating temperature range is -20°C to 85°C for optimal performance.
The A3955SB requires a single 5V supply voltage (VCC) and a separate ground (GND) connection. Ensure the power supply is stable and decoupled with a 0.1 μF capacitor.
The VREF pin is an internal voltage reference output that can be used as a reference voltage for external circuits. It is not necessary to connect VREF to anything, but it can be useful in certain applications.
The A3955SB can be configured for half-bridge or full-bridge operation by connecting the appropriate pins. For half-bridge, connect the HBEN pin to VCC. For full-bridge, connect the FBEN pin to VCC.
The A3955SB has a maximum current rating of 1.5 A per channel, but the actual current handling capability depends on the application and PCB design.
