LTC4352IMS#TRPBF

The LTC4352IMS#TRPBF is a high-performance, low-loss ideal diode controller with monitoring features, manufactured by Analog Devices Inc. (formerly Linear Technology). This device uses an external N-channel MOSFET to create a near-ideal diode, replacing high-power Schottky diodes and their associated heat sinks, thereby saving power and board area.

Key Features:

1. Low-Loss Replacement for Power Diode: The LTC4352IMS#TRPBF serves as a low-loss alternative to traditional power diodes, offering improved efficiency and reduced heat generation.
2. Ideal Diode Function: The device operates as an ideal diode, allowing for low-loss power ORing and providing hold-up applications. This ensures smooth current transfer and minimizes power loss.
3. Fast Turn-On and Turn-Off Times: With turn-on and turn-off times of 0.5 microseconds, the LTC4352IMS#TRPBF quickly responds to changes in the input power supply, reducing load voltage droop during supply switch-over and minimizing reverse currents if the input supply fails or is shorted.
4. Undervoltage and Overvoltage Protection: The controller provides undervoltage and overvoltage protection, disabling the power passage during these conditions to protect the circuit.
5. Open MOSFET Detect: The LTC4352IMS#TRPBF features an open MOSFET detect circuit that flags excessive voltage drop across the pass transistor in the on-state, indicating potential faults or issues.
6. Status and Fault Outputs: The device provides status and fault outputs, allowing for easy monitoring and troubleshooting of the circuit.
7. Reverse Current Enable Input: A REV pin enables reverse current, overriding the diode behavior when desired, providing additional flexibility in circuit design.
8. Package Options: The LTC4352IMS#TRPBF is available in 12-pin MSOP and DFN (3mm x 3mm) packages, making it suitable for a wide range of applications and board layouts.
