Application
applicationScheme description：
Solar triangle wall lamp is a common type of thermoelectric human induction application, using solar panels to charge lithium batteries, can detect day and night, standby energy saving during the day, and automatically light up when detecting someone moving at night, generally have a variety of modes, can be switched through the key.
There are several advantages in making charging night light scheme with HS6635CS：
1、 Compact peripheral devices
2、External three-terminal voltage regulator can be omitted,the probe can be powered by the chip's own LDO
3、It can save the driving triode /MOS tube,Chip REL pin output capacity up to 80MA
4、Programmable, customizable function, flexible to use
Function description：
Key sequence: OFF → Long light 30% → Induction /10% → Induction/OFF → OFF → Cyclic power-on enters OFF by default
The file function：
1、Induction/off: at the beginning, the heat engine is 100% for 15s and then off, and then the induction is started. After that, the induction is 100% delayed for 15s, and the induction refresh time can be repeated. 15S End Off.
2、Induction /10% : At the beginning of the 10% light 2-3S, start the induction, after the induction 100% delay 15s, can repeat the induction refresh time. 10% at the end of 15S.
3、Long bright: 30% long bright, no induction.
4、OFF: turn it OFF
Solar light control：
When the solar foot is greater than 1.2V(set according to the actual solar panel), the light is off. When it is less than 0.5V(according to the actual solar panel), return to the previous mode.
Over-protection：
When the battery power is lower than 2.65V, the light is off. Until the day charge to 3V after the night back to the previous mode.

Key parameters of the whole machine：
1、The scheme has a maximum output of 80MA (more than 80MA for lampholders is recommended with a transistor/MOS transistor driver)
2、The PWM frequency is 129HZ when the light is not full
3、Shutdown current (in OFF mode) 17UA
3、Standby current (induction/off mode, non-trigger state) 30UA
