■【Lithium-ion Battery Protection IC S-19192 Series】
Ultra-Low Current Consumption
A Simple Configuration Capable of Standalone Monitoring Provided with a Self-diagnosis Function for Failure Detection
This is a 3 to 6-serial cell battery monitoring IC with
a standalone monitoring function and self-diagnosis (self-test) function.
Since the current consumption during operation is 18μA (max.), it can also be used in systems with strict standby current restrictions.
Overcharge detection voltage accuracy: 2.5 to 4.5V (±20mV)
Overdischarge detection voltage accuracy: 1.5 to 3.0V (±80mV)

■【Convenience Timer S-35720
A Series】
Ultra-Low Current Consumption
Alarm Interrupt Function
Intermittent Operation Greatly Reduces System Standby Current
This is a convenience timer with a hardware timer setting that allows the user to select alarm interrupt times using time setting pins. Thanks to its ultra-low current consumption of 0.2uA, this timer IC can replace the internal timer of a microcontroller (MCU) , which helps to greatly reduce standby current by operating the system intermittently.
Operating voltage range: 1.8 V to 5.5 V
