10.2 Power Dissipation

Power dissipation = I² × R_DS(on) (total). For 1.5A continuous: P = (1.5)² × 0.45Ω ≈ 1.01W. At 25°C ambient, the SOP-8 package (θJA ≈ 120°C/W) will reach 1.01 × 120 + 25 = 146°C. Reduce current or add a heatsink for continuous >1A operation.

11. Typical Performance Graphs (Illustrative)

• R_DS(on) vs. Temperature: Increases 1.5x from 25°C to 125°C.
• Max Output Current vs. Ambient Temp: 1.5A at 25°C, derate to 0.8A at 85°C.
• Standby Current vs. VCC: <1µA up to 12V.

8. Important Design Notes

1. Heat Dissipation: At continuous current > 1A, a thermal pad or airflow is recommended. The IC will enter thermal shutdown (~150°C) and auto-recover.
2. Ground Separation: Connect PGND (motor current) and GND (logic) at a single star point near the power supply to avoid logic glitches.
3. PWM Frequency: Use 20–50 kHz for audible noise reduction. Lower frequencies (e.g., 1 kHz) reduce switching losses but may cause motor whine.
4. Back-EMF Diodes: The MX1616 includes internal parasitic diodes; external Schottky diodes are not required for low-current motors (<1A) but improve reliability for inductive loads.
5. VS vs. VCC: VM can be higher than VCC. For example, VCC = 5V (logic), VM = 12V (motor).

1. Operating Voltage (VM)

• Range: Typically 2V to 10V (or 12V depending on the specific revision).
• Application: This powers the motors. If your motors are rated 6V, you would supply 6V to this pin. The driver has a built-in Low Voltage detection, typically around 2.1V, below which it will cut output to protect the motor.

Calculating Maximum Current

The Mx1616 uses a reference voltage (VREF) internally. If your board provides a VREF pin:

IOUT_max = VREF / (8 × Rsense)

Example: If Rsense = 0.1Ω and VREF = 1.28V → IOUT = 1.28 / (8 * 0.1) = 1.6A. Dual-channel motor control : The Mx1616 can control
