ABSOLUTE MAXIMUM RATINGS Parameter Rating Unit Positive Supply Voltage (VCC) 3.6 V Maximum Voltage on +12VIN Pin 16 V Maximum Voltage on +5.0VIN Pin 6.25 V Maximum Voltage on SDA, SCL, THERM (Pin 22) and GPIO1−5 Pins 3.6 V Maximum Voltage on all Tach and PWM Pins +5.5 V Voltage on Remaining Input or Output Pins −0.3 to +4.2 V Input Current at Any Pin ±5 mA Package Input Current ±20 mA Maximum Junction Temperature (TJ MAX) 150 °C Storage Temperature Range −65 to +150 °C Lead Temperature, Soldering IR Reflow Peak Temperature Pb-Free Peak Temperature Lead Temperature (Soldering, 10 sec) 220 260 300 °C ESD Rating 1,500 V Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. NOTE: This device is ESD sensitive. Use standard ESD precautions when handling. Table 2. THERMAL CHARACTERISTICS (Note 1) Package Type qJA qJC Unit 24-lead QSOP 122 31.25 °C/W 1. JA is specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. Table 3.
