IR6210S is one of the most widely used PMIC (power management integrated circuit) products in PMIC - power distribution switches, load drivers category. This product is produced by Infineon Technologies, and it is widely used in electronic control systems, such as industry control equipment, motor control equipment, and power conversion systems, etc.In this article, we will explore the application field and working principle of IR6210S.Application FieldIR6210S is ideal for applications requiring high current drive capability. It is widely used for industrial applications such as robotics, power tools, motor drive, HVAC and factory automation. It is also suitable for automotive applications such as electric power steering and engine control.Due to its ruggedness and low on-resistance switch characteristics, it is also an ideal choice for white goods and battery management applications.Working PrincipleIR6210S is a dual-channel power switch that uses a P-type and N-type MOSFET to provide floating channels, Current limit and thermal shutdown protection functions. The switch output can be controlled either by voltage or current signals.When the voltage at the P-MOSFET gate is higher than the voltage at the N-MOSFET gate, the switch is in on-state and the current flows from drain to source. When the voltage of the P-MOSFET is lower than the voltage of the N-MOSFET, the switch is in off-state and the current cannot flow through the switch.To protect the switch from over-current, the IR6210S can drive internal current sense resistor in order to limit the current flowing through the switch. If the current exceeds a certain set threshold, the switch will automatically shut down to protect the circuit from damage.The switch also has thermal shutdown protection feature which enables proper thermal management. When the power dissipation goes beyond a certain level, the thermal shutdown will turn off the switch in order to avoid overheating.ConclusionIn conclusion, the IR6210S is a versatile and rugged dual-channel power switch. It´s well-suited for various industrial, automotive and white goods applications requiring high current drive capability. It has current limit and thermal shutdown protection features to protect the circuit from damage. This device provides an excellent solution for power management applications.
