STMicroelectronics PM8851
The PM8851 device is a high frequency single channel low-side MOSFET driver specifically designed to work with digital power conversion microcontrollers, such as the STMicroelectronics STLUX™ family of products. The PM8851 has complementary output pins to differentiate sink and source driving with a current capability of respectively 1 A and 0.8 A. The input levels of the driver are derived by the voltage present at the IN_TH pin (between 2 V and 5.5 V).- Min Voltage : 11V
- Max Voltage : 18V
- Channels : 1
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C
