CS464 CS464 Single Coil Predriver Features Description The CS464, Single Coil Predriver, provides interface control for the current through a primary ignition coil. Features include output current control, input nega- tive edge filtering, stall timing and over-voltage shutdown. The IC is available as a bumped flipchip or packaged in a 16 lead SO wide package. ■ 40mA Driver ■ Stall Timing ■ Output Clamp ■ Overvoltage Shutdown Absolute Maximum Ratings Lead Temperature Soldering Reflow (SMD styles only)...........60 sec. max above 183¡C, 230¡C peak Continuous Power Supply @ VBAT, -40¡C < TA < 55¡C .............5V to 24V Continuous Power Supply @ VBAT, 55¡C < TA < 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-normal ÒRun ModeÓ operation is 45 hours cumulative life not exceeding a continuous run time of 10 minutes with a 10 minute ÒOffÓ time following each successive operating cycle.
