IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise

noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA

Standard Conditions Unless otherwise indicated, all of the following tables are: VSO = VHI = 5V, RSET = 620Ω, RFREQ = 4.7kΩ,

RLOAD-IOUT1/2 = 8Ω to GND, RLOAD-BLUE = 10Ω to VHI, PMAX = 0x3FF, Reg 1-21 = 88h, Reg x-00 bit6 = 0, TA = +25°C.

Absolute Maximum Ratings (TA = +25°C)
