NJW4810A

NJW4810A Dual Half Bridge Driver ■ GENERAL DESCRIPTION The NJW4810A is a general-purpose dual half bridge driver capable of supplying 1A current. Output duty=100% can be operated by high side P channel MOSFET. It can use as a full bridge driver by connecting VDD1 and VDD2. The internal gate driver drives high-side/low-side power MOSFET; therefore, it is able to fast switching. Additionally, it has protection features such as over current protection and thermal shutdown. And in the case of failure, it can output a fault flag. It is suitable for power switching applications of DSP/micro controller. ■ FEATURES Output Switch Current 1A Operating Voltage 8.0V to 40V Thermal Shut Down Over Current Protection Under Voltage Lockouts Fault Indicator Output High Heat Radiation Package Package Outline HSOP8 ■ PACKAGE OUTLINE NJW4810AGM1 ■ PIN CONFIGURATION 18 27 36 45 Exposed PAD on backside connect to GND 1.
