The S-35710M is suitable for time management during system sleep periods*3 after engine shut-down. The alarm time can be programmed in one-second increments from one second to 194 days. Using this timer with its ultra-low current consumption of only 250nA typical, reduces the system standby current.
Influenced by fuel evaporative emission regulations, including EURO 6*4 (Europe), demand for periodic status management during engine shut-down is critical. In addition, blank detection capability is required for electric vehicles to monitor the status of the battery when it is not in use or while charging.
The S-35710M comes in a lead-free and halogen-free 8-pin HSOP-8Q package.
*1 | Relative time: The time interval from the time when an event occurs: e.g. “output an interrupt signal at xx minutes after the MCU stops.” | |
In contrast, absolute time denotes clock time: e.g. “Output an interrupt signal at xx:xx AM/PM every day.” |
||
*2 | 2-in-1: A type of package that is made up from two components (a timer IC and a Quartz Crystal). | |
*3 |
During system sleep periods: The period while the electronic control unit (ECU) is in sleep mode (power saving mode). |
|
*4 | EURO 6: European regulations that define the emission regulatory values of air pollutants from automobiles, which includes the fuel evaporative emission regulations. | |
To manage these values, time measurement during engine shut-down is important. | ||
