Absolute Maximum Ratings (Notes 1, 2, 3)

Output Voltage (VOUT) .............................................. 50V

Logic Supply Voltage Range (VDD) ............... 4.5V to 15V

Load Supply Voltage Range (VBB) ................ 5.0V to 50V

Input Voltage Range (VIN) ................. â0.3V to VDD+0.3V

Continuous Collector Current (IC) ........................ 500mA

Package Power Dissipation ............................. see graph

Operating Temperature Range (TA) ...... â55Â°C to +125Â°C

Storage Temperature Range (TS) ......... â65Â°C to +150Â°C

Note 1: TA = 25Â°C

Note 2: Derate at the rate of 20mW/Â°C above TA = 25Â°C.

Note 3: Micrel CMOS devices have input-static protection but are

susceptible to damage when exposed to extremely high static

electrical charges.
