Key Differentiators

  • Integrated current sense output in AKTR-E variant (vs VNQ5050KTR-E)
  • AEC-Q100 qualification (vs BTS50055-1TMA)
  • Low standby current (vs BTS50055-1TMA)

Design Notes

The PowerSSO-12 package has an exposed pad that must be soldered to a large copper area on the PCB to ensure adequate heat dissipation. For continuous operation at 13 A, the power dissipation can be significant, so it is recommended to use a copper pour of at least 2 square inches on the top and bottom layers, connected with thermal vias. The thermal resistance (theta_JA) is approximately 40Β°C/W, so at 2W dissipation, the junction temperature rise is 80Β°C. Ensure the ambient temperature is within the operating range to avoid thermal shutdown.

Place a 100 nF ceramic capacitor close to the VCC pins and a 10 Β΅F electrolytic capacitor for bulk decoupling. The input pin should be driven with a logic-level signal, and a pull-down resistor (e.g., 10 kΞ©) is recommended to ensure the device is off during power-up. The status pin should have a pull-up resistor to VCC to provide a valid logic level. Keep the traces for the output and VCC as short and wide as possible to minimize inductance and resistance.

Do not exceed the maximum supply voltage of 36 V, as this can damage the device. Ensure the load is connected correctly, as reverse polarity can cause damage. The device has loss of ground protection, but it is still important to ensure a solid ground connection. When driving inductive loads, the fast demagnetization feature handles the back-EMF, but it is recommended to add a freewheeling diode for additional protection in high-energy applications. Also, avoid driving the input with voltages above the specified logic level range.
