Frequently Asked Questions
How does the 92 mΩ Rds(on) of CSD25302Q2 affect power dissipation in a 5 A load-switch application?
At the maximum rated drain current of 5 A, the CSD25302Q2 dissipates approximately P = I² × Rds(on) = 25 × 0.092 = 2.3 W of conduction loss. The SON-6 thermal resistance to ambient is typically around 50 °C/W, so junction temperature rise would be roughly 115 °C above ambient, requiring adequate airflow or a copper pour to keep the device within its operating limits.
For which battery-powered high-side switch topologies does the -20 V Vds rating of CSD25302Q2 provide sufficient margin?
The -20 V drain-source breakdown voltage accommodates high-side switches powered from 1-cell Li-ion (4.2 V), dual-cell Li-ion (8.4 V), and 12 V lead-acid batteries with a comfortable safety margin of at least 8 V. This makes the CSD25302Q2 suitable for USB power switches, reverse-battery protection, and low-voltage motor H-bridge applications where peak transient voltages remain below -20 V.
What is the significance of the avalanche rating on CSD25302Q2 for inductive load driving?
Avalanche rating means the CSD25302Q2 can absorb energy stored in an inductive load—such as a relay coil or small motor—when the MOSFET turns off and the voltage spike exceeds -20 V. This eliminates the need for an external snubber diode in many designs, reducing BOM by 1 component and allowing inductive currents up to the device-specified avalanche energy limit without catastrophic failure.
