The output current regulation trip point
(ITRIP) is configured with the voltage on VREF pin. If VREF does not
exceed 3.3 V, VREF = ITRIP x 0.66 V/A. If ITRIP is 4 A, then VREF
should be set to 2.64 V. When VREF exceeds 3.3 V, the device can deliver even higher
peak current - up to 6.4 A when VREF is at 5 V. VREF can be generated with a simple
resistor divider from the DVDD.
