Description
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. Application Diagram Absolute Maximum Ratings 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 ÒRun ModeÓ operation is 45 hours cumulative life not exceeding a continuous run time of 10 minutes with a 10 minute ÒOffÓ time follow- ing each successive operating cycle. 1MB NC NC CR IN+ NC NC Gnd CS S NC OUT IC D NC VCC Flip-Chip
