Notes: 1. Operating voltage range is 10.2 V to 13.8 V.
2. Operating voltage range is 4.25 V to 5.75 V
3. Applied to Pin 40, 41, 42, 44, 56, 57 and pin 62
4. Operating junction temperature range is Tjop = 0°C to +125°C
5. ASO of upper and lower power transistor are shown below. Operating locus must be within the ASO.
6. The OTSD (Over Temperature Shut Down) function is built in this IC to avoid same damages by over heat of this chip. However, please note that if the junction temperature of this IC becomes higher than the operating maximum junction temperature (Tjopmax = 125°C), the reliability of this IC often goes down.
7. Thermal resistance: qj-a35°C/W with 6 layer multi glass-epoxy board.
· Soft Switching Driver Small Surface Mount Package: FP-80E (QFP80 Pin) Low thermal resistance: 35°C/W with 6 layer multi glass-epoxy board
· Low output saturation voltage
