The S-8200ADA-I6T1U is a power management integrated circuit (PMIC) that falls into the category of battery management. It offers a variety of features that enable the control, management and protection of low-power battery-powered applications. It is ideal for extended battery life in ultra-low, cost sensitive, battery-powered application systems.

The S-8200ADA-I6T1U support a main battery voltage of 1.8-6V and offers several features to better manage power and optimize performance from the battery. It has an array of individual features that can be individually enabled, each of them playing a role to manage power utilization from the battery and protect from overcharging, overdischarging, short-circuiting, and more.

Its typical application fields include digital still cameras, MP4 players, medical equipment, portable gaming systems, and other handheld device applications. It is designed to streamline battery management system designs and reduce BOM costs.

Basic Working Principle

The basic working principle of the S-8200ADA-I6T1U is to monitor the battery voltage and performs certain operations when the voltage exceeds certain levels. It includes a voltage detector, which monitors the battery voltage and feeds the signal to its embedded control logic, which then determines the appropriate response according to the pre-programmed thresholds set.

The controller then sends signals to the load switch and the charger. The load switch then disconnects the load from the main battery and the charger initiates charging when charging is necessary. Both are disabled under normal operation, i.e. when the battery voltage is within the desired range.

Moreover, it features over-voltage protection, which prevents the battery from overcharging by disconnecting it from the charger when the battery voltage reaches a certain level, and over-discharge protection, which prevents the battery from being over-discharged by disconnecting it from the load when the battery voltage reaches a certain level.

It also offers short-circuit protection, which prevents a device connected to the battery from being damaged or malfunctioning due to a short circuit, and under-voltage lock-out (UVLO) protection, which disables the load if the battery voltage falls below a pre-programmed threshold.

Moreover, the S-8200ADA-I6T1U also offers various charging options, such as pre-charge, fast-charge, trickle-charge and automatic recharge, which allows the user to choose the most suitable charging method according to the specific application.

Overall, the S-8200ADA-I6T1U is an advanced power management integrated circuit (PMIC) that provides efficient control, management and protection functions for battery-powered applications. It is suitable for a wide range of applications, including digital still camera, MP4 players, medical equipment, portable gaming systems and other handheld device applications.
