Detailed description

L99PM62GXP

20/102

Doc ID 17639 Rev 4

From V1 standby mode, the L99PM62GXP wakes up (after the selected timer has elapsed)

and sends an interrupt signal (via RxDL/NINT pin) to the µC. The device enters active mode

and the watchdog is started with a long open window. The microcontroller can send the

device back into V1 standby after finishing its tasks.

From VBAT standby mode, the L99PM62GXP wakes up (after the selected timer has

elapsed), turns on the V1 regulator and provides an NReset signal to the µC. The device

enters active mode and the watchdog is started with a long open window. The

microcontroller can send the device back into VBAT standby after finishing its tasks.

Supply the processor in low current mode.

Only active when selected via SPI.

Unless disabled by SPI.

The bus state is internally stored when going to standby mode. A change of bus state leads a wake-up after exceeding of

internal filter time (if wake-up by LIN or CAN is not disabled by SPI).

ON in fail-safe condition: If Standby mode is entered with active Fail Safe mode, the output remains ON in Standby mode.

Activation = ON if cyclic sense is selected.

cyclic activation = pulsed ON during cyclic sense.
