American Technical Support: 800-282-9855 Web Site: www.cherry–semi.com ARCHIVE DEVICE NOT RECOMMENDED FOR NEW DESIGN The CS464, Single Coil Predriver, provides interface control for the current through a primary igni- tion coil. Features include out- put current control, input nega- tive edge filtering, stall timing and over-voltage shutdown. The IC is available as a bumped flip- chip or packaged in a 16 lead SO wide package. Lead Temperature Soldering Over the extended ranges of temperature, voltage, and frequency not covered by normal operating conditions, low frequency and run related functions are allowed an additional 20% on specification limits. The degradation shall not be permanent, and upon returning to normal operating conditions shall be within the specification limits. Non-nor- mal “Run Mode” operation is 45 hours cumulative life not exceeding a continuous run time of 10 minutes with a 10 minute “Off” time follow- ing each successive operating cycle. 12V 0V 40Hz VIN RIN+ 10k RMB 10.7k CR 0.1µF 50V ZD 18V CV CC 0.1µF RD, 55Ω , 5W RV CC , 330 CS464 RIC2 RIC1 200CS 0.47µF 50V RS1 RS2 0.05Ω , 5W Adjust for 6.5A Coil Current MB NC NC CR IN+ NC NC Gnd CS S NC OUT IC D NC VCC VBAT
