Notes: 1. Operating voltage range is 4.25 V to 5.5 V. If power supply voltage exceed this operating range
in actual application, the reliability of this IC can not be guaranteed.
2. Operating voltage range is 10.2 V to 13.8 V.
3. ASO (Area of Safety Operation) of each output transistor is shown in figure 10.
Operating locus must be within the ASO.
4. Applied to CLK, COMM, SPNCTL, VIPWMH, VIPWML, SCLK, DATA and SEENAB.
5. Thermal resistance θj-a ≤ 30°C/W (Using 4 layer glass epoxy board)
6. Operating junction temperature range is 0°C to +125°C.
