1 (8) MAS6011 Solar Cell System Manager
- Power Down Indicator
- Low Battery Indicator
- Battery Overcharging Protection
DESCRIPTION
MAS6011 solar cell system manager monitors the supply voltage of a battery-powered system containing solar cells. Current consumption of this IC is extremely low. The solar manager uses three output signals to indicate the state of the system. Power Down (XPD) indicates whether the supply voltage is high enough to run the system. Low Battery (LB) is used to signal the situation where the battery is low. The third signal, SOL, is used for battery charging control. When the battery is full it bypasses the charging current by an internal switch to avoid overcharging of the battery. FEATURES APPLICATIONS
- Power Down Indicator
- Low Battery Indicator
- Battery Overcharging Protection
- Suitable for VL-type Rechargeable Lithium Batteries
- Solar Powered Watch

Make sure that GND is the first pad to be bo nded. Pick-and-place and all component assembly are recommended to be performed in ESD protected area. Note: If the die is to be placed on metal plane, the met al plane should be connected to GND or left floatin g because the substrate of the die is internally connected to GND. Note: Coordinates are pad center points where origin has been located in the center of the silicon die.

DA6011.000 4 (8) ABSOLUTE MAXIMUM RATINGS All voltages with respect to ground. Parameter Symbol Conditions Min Max Unit Supply Voltage VDD -0.3 6.0 V Voltage range for all pins -0.3 VDD+0.3 V Operating temperature T A -20 +60 oC Storage Temperature T S -50 +125 oC Stresses beyond those listed may cause permanent damage to the device. The device may not operate under these conditions, but it will not be destroyed. This is a CMOS device and therefore it should be handled carefully to avoid any damage by static voltages (ESD).
