LTC4412HVIS6#TRMPBF

LTC®4412HV is a low loss PowerPath™ controller in ThinSOT that controls an external P-channel MOSFET to create a near-ideal diode function for power switchover or load sharing. This permits highly efficient OR’ing of multiple power sources for extended battery life and low self-heating. When conducting, the voltage drop across the MOSFET is typically 20mV. For applications with a wall adapter or other auxiliary power source, the load is automatically disconnected from the battery when the auxiliary source is connected. Two or more LTC4412HVs may be interconnected to allow load sharing between multiple batteries or charging of multiple batteries from a single charger. This is an extended supply and temperature range version of the LTC4412. Application includes industrial and automotive applications, notebook and handheld computers, USB-powered peripherals, uninterruptable power supplies, logic controlled power switches.

• Reverse battery protection
• Automatic switching between DC sources
• Simplifies load sharing with multiple batteries
• Reverse battery protection
• Drives almost any size MOSFET for wide range of current requirements
• MOSFET gate protection clamp, manual control input
• Operating supply range from 2.5 to 36V (VIN and VSENSE must be in this range for proper operation)
• Typical GATE clamp voltage is 7V (apply IGATE = 1µA, VIN = 12V, TA = 25°C)
• 6-lead plastic TSOT-23 package
• Temperature rating range from -40°C to 125°C
