QFN-8 (4mmx4mm) ................ 47........7 ....°C/W

Notes:

1) Exceeding these ratings may damage the device. The

repetitive pulse rating is guaranteed for period of 100ns or

less with a maximum repetition rate of 1000kHz when VDD

is 15V or less.

2) DRVH and DRVL are outputs pins, cannot be connected to

external supply voltage.

3) The maximum allowable power dissipation is a function of the

maximum junction temperature TJ (MAX), the junction-to-

ambient thermal resistance θJA, and the ambient temperature

TA. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by PD (MAX) = (TJ

(MAX) - TA) / θJA. Exceeding the maximum allowable power

dissipation produces an excessive die temperature, causing

the regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

4) The device is not guaranteed to function outside of its

operating conditions.

5) Measured on JESD51-7, 4-layer PCB.
