The figure shows the IR4010 internal schematic box circuit, which indicates the internal circuit components of IR4010 device. It should be noted that it provides the VCC (voltage input response) with over or under voltage protection. When the VCC is equal to16 V, the control circuit starts to work with 6 V lag lock function. It refers that the circuit does not work with under-voltage protection when the VCC is less than (including) 10V. When the VCC is larger than 22V, the circuit does not work the either but with over-voltage protection. Comparator COMP1 controls the on-and off of the MOSFET. When the VTH (1) is larger than (including).7 V, turn off the MOSFET. Comparator COMP2 controls the connection of the MOSFET. When VTH (2) is less than (including) 1.45 V, the MOSFET is connected.
