Description
General part information
L9678P-S Series
The L9678P IC is a system chip solution targeted for emerging market applications. Base system designs can be completed with the L9678P, SPC560Px microcontroller and an on-board acceleration sensor or PSI5 sensor.
Energy reserve voltage is derived through a cost effective high frequency boost regulator. High frequency operation allows the user to pick up low value and cheap inductance. The voltage is programmable to 23 V or 33 V nominal.
Battery voltage is sensed through the VBATMON pin providing start-up and shutdown control for the system. Once battery voltage drops below the minimum operating voltage, the device enables the integrated crossover switch to permit orderly shutdown.
