5.3 Power Output
The slew rate of the voltage on the pins OUT1 and OUT2 are programmable via the SPI
interface. The fast settings are intended for fast switching solenoids (low inductance) to
minimize power dissipation within the TLE
7241E, and to minimize DC current error due
to overshooting the switch points. The slower slew rates can be used with slower
switching solenoids (high inductance) to improve radiated emissions from the wiring
harness.
