RECOMMENDED OPERATING CONDITIONS
(all voltages referenced to GND = 0 V)
PARAMETER MIN. TYP. MAX. UNIT
Input voltage (VIN) 4.5 - 60 Control input voltage (VCIN) (1) 4.5 - 60 Enable (EN) 0 - 60 V Bias supply (VDD) 4.7 5 5.25 Drive supply voltage (VDRV) 4.7 5.3 5.55 Output voltage (VOUT) 0.8 - 15
Temperature
Recommended ambient temperature -40 to +105 °C Operating junction temperature -40 to +125
Note
(1) For input voltages below 5 V, provide a separate supply to VCIN of at least 5 V to prevent the internal VDD rail UVLO from triggering
