TLE 7241E
Functional Description and Electrical Characteristics
Data Sheet 31 Rev. 1.1, 2009-01-19
Note that the switching frequency and duty cycle of the output transistor are not directly
controlled by the TLE 7241E device and are dependent on the characteristics of the
solenoid (inductance, resistance, etc.) and the solenoid supply voltage.
