www.ti.com SNVS679B – NOVEMBER 2010 – REVISED MARCH 2013 LM5050-2 High Side OR-ing FET Controller
Check for Samples: LM5050-2 FEATURES DESCRIPTION The LM5050-2 High Side OR-ing FET Controller
operates in conjunction with an external MOSFET as
an ideal diode rectifier when connected in series with
a power source. This OR-ing controller allows
MOSFETs to replace diode rectifiers in power
distribution networks thus reducing both power loss
and voltage drops. 1 2 Wide Operating Input Voltage Range: +6V to
+75V
+100 Volt Transient Capability
Charge Pump Gate Driver for External NChannel MOSFET
MOSFET Diagnostic Test Mode
Fast 50ns Response to Current Reversal
2A Peak Gate Turn-off Current
Minimum VDS Clamp for Faster Turn-off
Package: SOT-6 (Thin SOT23-6) The LM5050-2 controller provides charge pump gate
drive for an external N-Channel MOSFET and a fast
response comparator to turn off the FET when
current flows in the reverse direction. The LM5050-2
can connect power supplies ranging from +6V to
+75V and can withstand transients up to +100V. APPLICATIONS The LM5050-2 also provides a FET test diagnostic
mode which allows the system controller to test for …
