(1PCS) Sukam FL/SH 900 DIP MICROCONTROLLER IC

​Key Features & Description

​Package Type: Typically a 28-pin DIP (Dual In-Line Package) IC, making it easy to replace on the PCB.

​Application: Specifically programmed for the 900VA / 12V Su-Kam Sine Wave inverter models.

​Core Logic: It uses Fuzzy Logic computing to control battery charging, which helps in extending battery life by preventing overcharging and managing deep discharge.

​Waveform Control: It generates the PWM (Pulse Width Modulation) signals required to create a clean sine wave output, making it safe for sensitive electronics like laptops and LED TVs.

​Functions of the IC

​The IC manages the following critical operations:

​Mains Sensing: Detects when the grid power is available to switch between “Battery Mode” and “Mains Mode.”

​6-Stage Charging: Controls a multi-stage charging process to optimize battery health.

​Protection Suite: Monitors for Overload, Short Circuit, Low Battery, and Over Temperature conditions.

​Display Driver: Sends signals to the LED/LCD panel to show status (e.g., “Charging,” “Inverter ON,” or “Low Battery”).
