Electrical characteristics

Conditions: VIN=12 V, VDD_DRIVER=7.5 V, VDD=5 V, VLDO_3V3=3.3 V, VLDO_1V8=1.8 V, TJ from -40°C to

125°C, CLSn_GD=CHSn_GD=1 nF, CBRIDGE_VREF=10 nF, LBUCK=10 μH, CLDO_1V8=1 μF, CLDO_3V3=4.7 μF,

CBUCK=10 μF (ceramic capacitor), CEXT=6.8 nF, REXT=100 kohm (CEXT with REXT is AC coupling network

on RING_NODE_SNS), CQFDRV_VRING=2.2 nF (coupling cap for Q-factor measurement), LBUCKBOOST=3.6 μH,

CD+=CD-=100 pF; unless otherwise noted.

Typical values are tested at TJ = 25°C, minimum and maximum values are guaranteed by thermal

characterization in the temperature range of -40 to 125°C, unless otherwise specified.
