As the current level continues to increase in automotive electronic systems, designers can no longer use conventional blocking Schottky diodes due to high power dissipation and thermal issues. The LT8672 is an active rectifier controller with reverse current protection that can replace the diode.
The LT8672 operates at the input range between 3V and 42V with only 20uA quiescent current. It protects the load against reverse input voltages up to -40V. It’s low power dissipation, fast transient response, and small solution size make the LT8672 ideal for automotive applications.
The LTC7000 is a fast, protected, high side N-channel MOSFET gate driver that contains an internal charge pump allowing the external N-channel MOSFET to stay on indefinitely. The LTC7000 receives a low voltage digital input signal and can fully turn-on or turn-off a high-side N-channel. The LTC7000 includes protection features for the power source, external MOSFET and load such as overcurrent trip, fault flag, under voltage and over voltage lockouts.View the Video
As automotive electronic content increases, voltage regulators continually need smaller size, higher current, and lower radiated emissions. Silent Switcher® 2 products address this need by providing 2MHz solutions with high efficiency without compromising EMI performance. The LT8650S is a dual channel, 42V step-down regulator providing up to 4A of output current per channel in a 4mm × 6mm package. Silent Switcher® 2 technology makes the EMI performance less dependent on PCB board layout, enabling robust EMI results. Switching losses are not compromised for EMI performance, as fast rising edge control approaching 10V/ns is achieved with very low overshoot and ringing.View the Video

The LTM4643 is a quad output step-down µModule® (power module) regulator, configurable as a single output (12A), dual (6A & 6A or 9A & 3A), or quad (3A each) regulator in a 9mm x 15mm x 1.82mm ultrathin LGA package. This flexibility enables system designers to rely on one simple and compact µModule regulator for a variety of voltage and load current requirements in FPGA, GPU, ASIC and processor-based applications. The 1.82mm height ultrathin package allows the LTM4643 to be mounted on the backside of the PCB, freeing space on the topside for components such as memory and connectors. The LTM4643 is suitable for systems with height restrictions, such as backside PCB assembly in PCIe applications and where the regulator must fit under a common heat sink or cold plate to cool high power FPGAs, GPUs, ASICs and processors in applications such as embedded computing, data storage, medical imaging and industrial systems.View the Video
Many systems using a precision analog-to- digital converter to digitize signals need some signal conditioning circuitry between the signal source and the ADC. In addition to its other functions, that circuitry must accurately drive the input of the ADC. The combined demands of performance and high speed to handle the ADC input currents can present a substantial additional design challenge. To simplify and improve these systems, the LTC2358 octal ADC adds FET-input analog buffers to the performance and flexibility of the LTC2348. These buffers allow the signal conditioning to be designed around the needs of the signal, rather than the needs of the ADC. The purely capacitive picoamp inputs can be directly connected to a variety of delicate, low-current sensors and ease the design of analog antialiasing filters and other functions.View the Video
Today, many electronic systems require power processing at higher voltages, while simultaneously demanding increased efficiency and low EMI/EMC emissions. The LTC7103 meets all of these challenges, with an unprecedented combination versatility and simplicity.
The LTC7103 is a 105V, 2.3A, synchronous step-down regulator that incorporates a proprietary architecture in a small 5mm x 6mm QFN package to achieve ultra-low EMI/EMC emissions without sacrificing efficiency. Operating from an input voltage between 4.4V and 105V, the LTC7103 has a no-load input current of only 2uA when regulating 48Vin to 3.3Vout.
Utilizing a unique average current mode architecture, the LTC7103 offers fast and accurate output current programming and monitoring without the need for an external sense resistor. Eight, pin-selectable fixed output voltages and optional internal loop compensation save board space and quiescent current while making the LTC7103 extremely easy to use.View the Video
The LTC2500-32 is a new and enabling approach to high-bandwidth, precision applications such as automated test equipment, control loops, seismology, and precision data acquisition. Analog performance of the SAR core is second to none - linearity is guaranteed 2 ppm maximum. Offset drift is 7 parts per billion per degree C, gain drift is 50 parts per billion, and the signal-to- noise ratio is 104dB at 1Msps. Such applications have traditionally used sigma delta ADCs, but the LTC2500 is much more versatile. Unlike a sigma delta ADC, the choice of digital filter is arbitrary, and the LTC2500-32 provides 78 filter options to suite a variety of applications. The filtered output achieves up to 148dB of dynamic range at 61sps. The LTC2500 also provides both no-latency data and filtered data simultaneously, matched perfectly in both time and analog accuracy.View the Video
The LTC3871 is a bidirectional synchronous buck or boost controller to step-down or step-up the voltage between the 12V and 48V batteries in dual battery automotive applications.
