Notes: 1. Survivability of device with transient voltage applied to VCC pin for a duration not to exceed 10ms.
2. Survivability of device with overvoltage applied to VCC pin producing the current for a duration not to
exceed 10ms.
3. Exceeding this voltage range on the function pin may cause permanent damage to the device.
4. A zener diode is incorporated across collector to emitter of the output NPN device to prevent voltage
overdrive of the external Darlington switch transistor.
5. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering.
Exceeding these limits may cause malfunction or permanent damage to the device.

Notes: 6. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For
Peak Package Reflow Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to
view all orderable parts. (i.e. MC33xxxD enter 33xxx), and review parametrics.
7. Advance Threshold Voltage is the positive (or negative) going voltage on Advance necessary cause the
Dwell Control voltage to positive (or negative) going transition 2.0V respectively. It is expressed as
VTH±(A)=VB+VX where VB is the Bias Voltage and VX is the additional voltage necessary to attain the
threshold.
8. Bypass Threshold Voltage is the positive (or negative) going voltage on Bypass necessary cause the Dwell
voltage to positive (or negative) going transition 1.5V respectively. It is expressed as VTH±(BP)=VB+VX where
VB is the Bias Voltage and VX is the additional voltage necessary to attain the threshold.
9. Increasing voltage on Current Sense which when attained will cause Dwell to transition low to 1.5V with a
10mA load.
10. EST Threshold Voltage is the positive (or negative) going voltage on EST necessary cause the Dwell
voltage to positive (or negative) going transition 1.5V respectively. It is expressed as VTH±(EST) and is in
reference to ground.
11. Ref/Dwell can either source or sink current; A minus sign denotes the Ref/Dwell is sourcing current.
12. Ref/Dwell Threshold Voltage (Bypass Mode) is the positive (or negative) going voltage on Ref/Dwell
necessary cause the Reference voltage to positive (or negative) going transition 1.5V respectively. It is
expressed as VTH±(RD)=VB+VX where VB is the Bias Voltage and VX is the additional voltage necessary to
attain the threshold.
13. Ref/Dwell Threshold Voltage (No Pump) is the positive (or negative) going voltage on Ref/Dwell
necessary cause the Dwell voltage to positive (or negative) going transition 1.5V respectively. It is
expressed as VTH±(RD)=VB+VX where VB is the Bias Voltage and VX is the additional voltage necessary to
attain the threshold. Advance=1.0V providing no input assist or "No Pump" influence of Dwell signal;
Reference open.
14. Ref/Dwell Threshold Voltage (Max Pump) is the positive (or negative) going voltage on Ref/Dwell
necessary cause the Dwell voltage to positive (or negative) going transition 1.5V respectively. It is
expressed as VTH±(RD)=VB+VX where VB is the Bias Voltage and VX is the additional voltage necessary to
attain the threshold. Advance=3.0V providing maximum input assist or Max Pump" influence of Dwell
signal; Reference=Dwell Control=open.
15. All pins open except Pwr Gnd with Dwell sinking 200mA.
16. Limit conditions with Dwell output NPN in the OFF condition.
17. Reference saturation voltage to ground with 0.3mA of current going into the Reference.
18. Dwell Control adjusts the reference voltage of Dwell Comparator.
19. Dwell Control. sourcing 100µA.
20. Dwell Control sinking 100µA.
21. Dwell Control at 3.0V; Internal Dwell Control transistor OFF.
22. Dwell Control at 3.0V; Internal Dwell Control transistor ON.
23. Dwell Control at 7.0V; Internal Dwell Control transistor OFF.
24. Measured with RPM Detect voltage at 0.5V to reflect maximum source current capability.
25. Measured with RPM Detect voltage at 0.5V and 1.5V to reflect maximum leakage current.
26. RPM Detect sinking 16µA.
27. Decreasing Threshold; RPM Detect voltage decreased from 0.6V until Dwell voltage transitions low to
1.5V with 10mA load.
