Motor driver ICs
Proposed device set delivers everything you need to design a simple Intelligent Power Module (IPM) of motor drives mainly targeting low power inverter-driven application like air conditioner and washing machine and fans.
The typical IPM is used high side driver high voltage ICs (HV ICs) and low side drivers IC and six MOSFET or six pair of IGBT+UFD. It combines optimized circuit protection and drive matched to low-loss IGBTs and MOSFETs. System reliability is further enhanced by the under-voltage lock-out and short circuit protection. The high speed HV ICs provides optocoupler-less single-supply IGBT (MOSFET) gate driving capability.

DC-DC converters and regulators
The main application of DC-DC regulators is power supply systems for different devices and gadgets including on-board supply systems. In the last time DC-DC converters are used widely as PoL DC/DC nearby power consumer that let improve the temperature conditions of whole system, decrease noise and increase reliability of power supply system.
DC-DC regulator is cover solutions for telecom, datacom, networking and peripherals as well as addressing the needs of laptop, desktop and server platforms and enterprise power.
