(1PCS) Microtek TX Model SQEB-SGP-V4R5 NEW Microcontroller IC 100% Warking

Yah microcontroller IC 18018 Ya 23023 Transformer wali kit ka hai

​Key Specifications & Features

​Model Number: SQEB-SGP-V3R5 (often abbreviated as V3.5 or V3R5).

​Package Type: DIP-28 (Dual In-line Package with 28 pins), making it easy to replace on the PCB.

​Inverter Type: Specifically programmed for Square Wave “TX” series models (e.g., Microtek EB 700, EB 900).

​Voltage System: Standard for 12V DC inverter systems.

​Functionality:

​Generates the Pulse Width Modulation (PWM) signal for square wave output.

​Handles Mains Sensing (detecting when electricity is available from the grid).

​Controls the Battery Charging algorithm (Trickle/Boost charging).

​Provides protection against Overload, Short Circuit, and Low Battery.

​Usage & Troubleshooting

​This IC is a direct replacement for damaged controllers on the inverter’s main logic board. Common symptoms of a faulty IC include:

​Inverter stuck in “Charging” or “Mains” mode.

​Constant “Overload” or “Low Battery” buzzer despite normal conditions.

​No output signal to the MOSFETs (inverter does not switch to backup mode).
