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)
