Conditions

Note 1: When using sense MOSFETs, it is recommended that RSENSE < 50Ω. Higher values may affect the sense

MOSFET’s current transfer ratio.

2: DC measurement.

3: Input switched from 0.8V (TTL low) to 2.0V (TTL high), time for gate transition from 0V to 2V.

4: Input switched from 0.8V (TTL low) to 2.0V (TTL high), time for gate transition from 2V to 17V.

5: Input switched from 2.0V (TTL high) to 0.8V (TTL low), time for gate transition from 20V (gate on voltage)

to 17V.

6: Input switched from 2.0V (TTL high) to 0.8V (TTL low), time for gate transition from 17V to 2V.

7: Frequency where gate on voltage reduces to 17V with 50% input duty cycle.

8: Gate on time tG(ON) and tG(OFF) are not 100% production tested.
