LM5050MK-1/NOPB Texas Instruments 热交换电压控制器 Hi Side OR-ing FET Cntlr

1 Features 3 Description

The LM5050-1/-Q1 High Side OR-ing FET Controller

1• Available in Standard and AEC-Q100 Qualified

operates in conjunction with an external MOSFET as Versions LM5050Q0MK-1 (up to 150°C TJ

) and

an ideal diode rectifier when connected in series with LM5050Q1MK-1 (up to 125°C TJ

)

a power source. This ORing controller allows

• Wide Operating Input Voltage Range, VIN: 1 V to MOSFETs to replace diode rectifiers in power

75 V (VBIAS required for VIN < 5 V) distribution networks thus reducing both power loss

• 100-V Transient Capability and voltage drops.

• Charge Pump Gate Driver for External N-Channel The LM5050-1/-Q1 controller provides charge pump

MOSFET gate drive for an external N-Channel MOSFET and a

fast response comparator to turn off the FET when • Fast 50-ns Response to Current Reversal

current flows in the reverse direction. The LM5050-1/-

• 2-A Peak Gate Turnoff Current Q1 can connect power supplies ranging from 5 V to

• Minimum VDS Clamp for Faster Turnoff 75 V and can withstand transients up to 100 V.

• Package: SOT-6 (Thin SOT-23-6)
