Features
• 2 μA shipment - DEEP SLEEP mode current and 5 μA standby consumption
(with VREG LDO active) standby consumption (with VREG LDO active)
• Integrated 3.3 V VREG LDO for supplying MCU and LEDs
• Measures cell voltage (3 to 5 cells), with over/undervoltage detection and
balance undervoltage protection
