The VIPERGAN100 is a high voltage converter, designed for medium power quasi-resonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters, capable to provide an output power up to 75 W in wide range and up to 100 W in European range or with a PFC in the front end. It integrates a complete set of features that provide an extremely flexible and easy to use chip and helps to design a highly efficient offline power supply. The ZVS quasi-resonant operation with the dynamic blanking time feature and the valley synchronization function, that turns on the power switch always at the valley of the drain resonance, reduces the switching losses and maximizes the overall efficiency at any input line and load condition. The advanced power management with the low quiescent helps to achieve low stand-by consumptions. The feed-forward compensation minimizes the maximum output peak power variation over the entire input voltage range. In addition to the above functions, the device offers protection features that considerably increase end-product’s safety and reliability: the output overvoltage protection (OVP), the overtemperature protection (OTP), the overload protection (OLP), the brown-in/out protection, that set the input voltage level to power on and power off the converter and the input overvoltage protection (iOVP), that protects the system in case of an abnormal increase of the input line. All the protections are auto-restart mode.

The VIPERGAN50 is a high voltage converter, designed for medium power quasi-resonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters, capable to provide an output power up to 50 W in wide range.

The VN9016AJ is a single channel high-side driver manufactured using ST proprietary VIPower M0-9 technology and housed in a PowerSSO-16 package. The device is designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, providing protection and diagnostics. The device integrates advanced protective functions such as load current limitation, overload active management by power limitation and overtemperature shutdown with configurable latch-off. A FaultRST pin unlatches the output in case of fault or disables the latch-off functionality. A dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic functions including high precision proportional load current sense, supply voltage feedback and chip temperature sense, in addition to the detection of overload and short circuit to ground, short to VCCand OFF-state open-load.

The VL53L1 is a laser-ranging ToF sensor. It covers applications requiring long distance ranging up to 800 cm (ranging mode), multizone ranging (scanning mode), and low-power (autonomous mode). A comprehensive application note (AN5573) provides technical details on the programming interface including its bare driver. The API (application programming interface) enables the device to be controlled and managed in these three modes, to meet the requirements of all applications. With patented algorithms and ingenious module construction, the VL53L1 is also able to detect different objects within the FoV (field of view). Its depth information (histogram) is at 60 Hz. Scene browsing and multizone detection are now possible with the VL53L1, thanks to a software customizable detection array. This provides a quicker "touch-to-focus", or minidepth map use cases.

The VL53L1-SATEL breakout boards can be used for easy integration into customer devices. Thanks to the voltage regulator and level shifters, the VL53L1 breakout boards can be used in any application with a 2.8 V to 5 V supply. The PCB section supporting the VL53L1 module is perforated so that developers can break off the mini PCB for use in a 2.8 V supply application using flying leads. This makes it easier to integrate the VL53L1-SATEL breakout boards into development and evaluation devices due to their small size.

The VL53L1X is a state-of-the-art, Time-of-Flight (ToF) laser-ranging sensor, enhancing the ST FlightSense product family. It is the fastest miniature ToF sensor on the market with accurate ranging up to 4 m and fast ranging frequency up to 50 Hz. Housed in a miniature and reflowable package, it integrates a SPAD receiving array, a 940 nm invisible Class 1 laser emitter, physical infrared filters, and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover glass options. Unlike conventional IR sensors, the VL53L1X uses ST’s latest generation ToF technology, which allows absolute distance measurement whatever the target color and reflectance. It is also possible to program the size of the ROI on the receiving array, allowing the sensor FoV to be reduced.
