CS464
Single Coil Predriver
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.

Absolute Maximum Ratings
Lead Temperature Soldering
Reflow (SMD styles only)...........60 sec. max above 183°C, 230°C peak
Continuous Power Supply @ V_BAT, -40°C < T_A < 55°C .............5V to 24V
Continuous Power Supply @ V_BAT, 55°C < T_A < 140°C.............6V to 18V
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.
