Control input
The control input (CI) pin is resistively pulled up RCI to the supply voltage VVS such that
VCI=VCI off and the glow plugs are switched off by default. The L9524C is controlled by
transitions of VCI from VCI off to VCI on (falling edge) and vice versa (rising edge). Voltage
level changes of VCI which last shorter than tCI fil are ignored.
In transistor mode (modes 3 to 6) the L9524C expects a PWM signal at the CI pin. Each
falling edge starts measuring its on time tCI on (time until next rising edge, i.e. length of this
low pulse) and its period TCI (time until next falling edge). The end of a pulse group is
detected if no falling edge occurs for a time greater than tCI to and the glow plugs are
switched off. Therefore, it is not possible to switch on the glow plugs permanently with one
exception: if the low voltage level of the first falling edge is greater than VCI to the glow plugs
remain switched on as long as this low pulse lasts.
