Note 1:
On-time specifications are measured from 50% point to 50% point at the DH pin with LX = PGND, V
BST
= 5V, and a 500pF
capacitor from DH to LX to simulate external MOSFET gate capacitance. Actual in-circuit times may be different due to
MOSFET switching speeds.
Note 2:
The trigger delay time, t
TRIG
, is measured from the time the TRIG pin transitions to the time when the DL pin goes low.
Note 3:
Production testing limitations due to package handling require relaxed maximum on-resistance specifications for the QFN
package.
Note 4:
The driver-disable delay time (t
DD
) is measured from the time the
DD
pin transitions to the time when the DL or DH pin tran-
sitions.
Note 5:
Specifications to -40
°
C and +100
°
C are guaranteed by design and not production tested.
