Key Differentiators

Higher continuous current rating (15A) than VNH7100ASTR (vs VNH7100ASTR)
Lower ON-resistance (40 mOhm) than VNH7100ASTR (vs VNH7100ASTR)
Wider supply voltage range (4V-28V) than BTN8982TA (vs BTN8982TA)

Design Notes

At 15A continuous current, the power dissipation is approximately 9W (I^2 * R = 15^2 * 0.04). The PowerSSO-36 package has a thermal resistance of 30 C/W, resulting in a 270C junction temperature rise. A heatsink or large copper area (at least 2 square inches) is required for reliable operation above 5A.

Place a 100nF ceramic capacitor close to the VCC pin and a 10uF electrolytic capacitor on the VS pin. The current sense pin (CS) requires an external resistor to set the gain; connect it to ground with a resistor value per the datasheet formula. Ensure the exposed pad is soldered to a large copper area for heat dissipation.

Do not exceed the absolute maximum supply voltage of 28V. Ensure the logic inputs are not left floating; use pull-down resistors. The DIAG pin is open-drain and requires a pull-up resistor. For PWM operation, avoid frequencies above 20 kHz to prevent excessive switching losses.
