Description
L9952GXP
Doc ID 13518 Rev 5
2.2
Power control in operating modes
The L9952GXP can be operated in 4 different operating modes:
●
Active
●
Flash
●
V1- standby
●
VBAT - standby
A cyclic monitoring of wake-up inputs is available in stand-by modes.
2.2.1
Active mode
All functions are available.
2.2.2
Flash mode
To disable the watchdog feature a FLASH program mode is available.
The mode can be entered by VPWM2 ≥ 9V
In this case all other functions are the same as in active mode
Watchdog can be disabled as well as soon as L9952GXP enters the V1 standby mode (see
section 2.9 for details)
Note:
“High” level for flash mode selection is VPWM2 ≥ 9V. For all other operation modes, standard
5V logic signals are required. For proper operation PWM1 must not be set to a voltage level
above standard 5V logic.
2.2.3
V1 standby mode
Outputs and internal loads are switched off. To supply the micro controller in a low power
mode, the voltage regulator1 (V1) remains active. The intention of the V1 standby mode is
to preserve the RAM contents. A cyclic contact supply and wake-up input sense feature (for
cyclic monitoring of external contacts) can be activated by SPI.
2.2.4
VBAT standby mode
To achieve minimum current consumption during VBAT standby mode, all L9952GXP
functions (except the ones for wake up functionality) are switched off.
In VBAT - standby mode the current consumption of the L9952GXP is reduced to 7A, typical
(without cyclic sense feature selected).
The transitions from active mode to either V1-standby or VBAT - standby are controlled by
SPI.
VBAT - standby mode is dominant; i.e. if both bits, V1 - standby and VBAT - standby are set to
“1”, the L9952GXP will enter VBAT - standby mode.
