Instructions for Using A3955SLBTR:
Supply Voltage (VCC):
- Ensure the supply voltage is within the range of 8V to 50V to avoid damage to the device.
- Use appropriate voltage regulation to maintain a stable supply.
Supply Current (ICC):
- The device draws approximately 40mA when all outputs are off and at room temperature.
- Ensure the power supply can handle this current plus any additional load current.
Output Current per Channel (IOUT):
- Each channel can handle up to 2.0A continuously at room temperature.
- For higher currents or temperatures, ensure adequate heat dissipation.
Maximum Power Dissipation (PD):
- The maximum power dissipation is 20W at room temperature.
- Use heatsinks or other cooling methods if operating near this limit.
Operating Temperature Range (TA):
- The device operates reliably between -40°C and 125°C.
- Avoid exceeding these limits to prevent performance degradation or failure.
Storage Temperature Range (TSTG):
- Store the device between -65°C and 150°C to ensure long-term reliability.
- Avoid exposing the device to extreme temperatures for extended periods.
Junction Temperature (TJ):
- The maximum junction temperature is 150°C.
- Monitor the junction temperature to avoid thermal shutdown or damage.
Thermal Resistance:
- RθJA (Junction to Ambient) is 35°C/W.
- RθJC (Junction to Case) is 2.0°C/W.
- Use these values to design effective heat dissipation solutions.
Additional Notes:
- Always refer to the datasheet for the most accurate and detailed information.
- Ensure proper PCB layout and grounding to minimize noise and interference.
- Use external components as recommended in the datasheet to optimize performance.
