The LM9061 family consists of charge-pump devices which provides the gate drive to an external power MOSFET of any size configured as a high-side driver or switch. This includes multiple parallel connected MOSFETs for very high current applications. A CMOS logic-compatible ON and OFF input controls the output gate drive voltage. In the ON state, the charge pump voltage, which is well above the available VCC supply, is directly applied to the gate of the MOSFET. A built-in 15-V Zener clamps the maximum gate to source voltage of the MOSFET. When commanded OFF a 110-µA current sink discharges the gate capacitances of the MOSFET for a gradual turnoff characteristic to minimize the duration of inductive load transient voltages and further protect the power MOSFET.
Lossless protection of the power MOSFET is a key feature of the LM9061. The voltage drop (VDS) across the power device is continually monitored and compared against an externally programmable threshold voltage. A small current-sensing resistor in series with the load, which causes a loss of available energy, is not required for the protection circuitry. If the VDS voltage, due to excessive load current, exceeds the threshold voltage, the output is latched OFF in a more gradual fashion (through a 10-µA output current sink) after a programmable delay time interval.

LM9061EVM — LM9061EVM 고압측 보호 컨트롤러 평가 모듈
The LM9061EVM evaluation module demonstrates high-side protection to a connected load from over-current and over-voltage conditions. An ON/OFF input controls the gate drive to a high-side MOSFET. Over-current protection is performed by monitoring the voltage drop (VDS) across the MOSFET, which is (...)
