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

Reflow (SMD styles only)...........60 sec. max above 183°C, 230°C peak

Frequency .......................................................................................5 to 400Hz

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.
