Automotive 1.5-V to 5.5-V, 1.5-A, 0.5-µA IQ ideal diode with integrated FET The LM66100-Q1 is a Single-Input, Single-Output (SISO) integrated ideal diode that is well suited for a variety of applications. The device contains a Pchannel MOSFET that can operate over an input voltage range of 1.5 V to 5.5 V and can support a maximum continuous current of 1.5 A. The chip enable works by comparing the CE pin voltage to the input voltage. When the CE pin voltage is higher than VIN, the device disables and the MOSFET is off. When the CE pin voltage is lower, the MOSFET is on. The LM66100-Q1 also comes with reverse polarity protection (RPP) that can protect the device from a miswired input, such as a reversed battery. Two LM66100-Q1 devices can be used in an ORing configuration similar to a dual diode ORing implementation. In this configuration, the devices pass the highest input voltage to the output while blocking reverse current flow into the input supplies. These devices can compare input and output voltages to make sure that reverse current is blocked through an internal voltage comparator.

4A Gate Driver RF Coupling 2500Vrms 1 Channel 8-SOIC Confirmed — this is a Skyworks (formerly Silicon Labs) Si827x-family isolated gate driver, single-channel, with deglitch and UVLO, in the "GBD" variant (3V UVLO threshold). Here's the spec. Engineering Specification — Si8271GBD-IS Manufacturer: Skyworks Solutions, Inc. (formerly Silicon Labs) Device Family: Si827x ISOdriver General Description The Si8271GBD-IS is a single-channel isolated gate driver integrated circuit manufactured by Skyworks Solutions, designed to drive power switching devices such as MOSFETs, IGBTs, and wide-bandgap SiC or GaN FETs in power conversion applications. The device uses Skyworks' proprietary silicon-based galvanic isolation technology rather than the optical isolation used in traditional optocoupler-based gate drivers, providing a more robust, longer-lasting, and more precisely matched isolation barrier between the low-voltage control circuitry and the high-voltage power switching stage. This isolation approach delivers several advantages over legacy optocoupler solutions, including significantly higher common-mode transient immunity, which allows the device to maintain reliable signal integrity even when subjected to the very fast voltage transients generated by high-speed switching in modern power converters. The device's high noise immunity prevents these switching-induced transients from corrupting the gate drive signal, eliminating a common failure mode in less robust isolated driver designs where fast edge rates can cause spurious switching or loss of control. The silicon isolation technology also provides tighter timing specifications, reduced timing variation across temperature and device lifetime, and better part-to-part matching than optocoupler-based alternatives, all of which contribute to more predictable and efficient power stage operation. The device includes an integrated de-glitch filtering circuit on its input, which screens out short noise spikes or unwanted transitions on the control input before they can be passed through to the gate drive output, improving overall system robustness in electrically noisy environments. Undervoltage lockout protection is built into the device, automatically disabling the gate drive output if the supply voltage falls below a safe operating threshold, protecting the driven power switch from being driven with insufficient gate voltage, which could otherwise lead to excessive conduction losses or device damage. The device also provides a dead-time programming feature, allowing designers to precisely tune the timing margin between switching transitions in half-bridge or similar topologies, helping to prevent shoot-through conditions while minimizing unnecessary dead time that would otherwise reduce converter efficiency. The Si8271GBD-IS operates from a wide input supply voltage range and supports drive voltages suitable for a broad range of gate drive requirements, making it adaptable to many different power switch types and converter topologies. It is built to operate reliably across a wide ambient temperature range, supporting use in demanding industrial, telecom, and renewable energy power conversion environments. The device is housed in a compact surface-mount package suited to dense power converter board layouts, and its construction reflects the long-life, high-reliability design philosophy that distinguishes silicon-isolation-based gate drivers from optocoupler-based alternatives.
