HVLED001BHigh power factor flyback controller with constant voltage primary sensing and ultra low standby consumption | LED Drivers | 1 | Active | The HVLED001B is an enhanced peak current mode controller able to control mainly high power factor (HPF) flyback or buck-boost. Some other topologies such as buck, boost and SEPIC, can also be implemented.
Primary side regulation and optocoupler control can be applied independently on the chip, both exploiting precise regulation and very low standby power during no load conditions.
The innovative ST high voltage technology allows direct connection of the HVLED001B to the input voltage in order to both start up the device and to monitor the input voltage, without the need for external components.
Abnormal conditions like open circuit, output short-circuit, input over-voltage or under-voltage and circuit failures like open loop and overcurrent of the main switch are effectively controlled.
A smart Auto Recover Timer (ART) function is built in to guarantee an automatic application recovery, without any loss of reliability. |
HVLED002High performance current mode LED controller | Power Management (PMIC) | 1 | Active | The HVLED002 control IC provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes to implement LED drivers. Internally implemented circuits include a trimmed oscillator for the precise duty cycle control, undervoltage lockout, a precision reference trimmed for accuracy at the error amplifier input, a PWM comparator which also provides current limit control and a totem pole output stage designed to the source or sink high peak current. The output stage, suitable for driving N-channel MOSFETs, is low in the off-state. |
HVLED101Advanced high power factor flyback controller with valley locking and maximum power control | Integrated Circuits (ICs) | 1 | Active | The HVLED101 is an enhanced peak current mode controller able to control mainly high power factor (HPF) flyback or buck-boost topologies having an output power up to 180 W. Some other topologies, like buck, boost and SEPIC could also be implemented. Primary Side Regulation of output voltage and Optocoupler control can be applied independently on the chip both exploiting precise regulation and very low standby power during no-load conditions. The innovative ST high-voltage technology allows to directly connect the HVLED101 to the input voltage in order to both start up the device and monitor the input voltage without the need of external components. Integrated valley locking feature guarantees noise free operation during medium and low load operation and maximum power control allows limiting the input power to a level programmable by the user to increase converter safety. Abnormal conditions like open circuit, output short-circuit, input overvoltage or undervoltage, external protection circuitries and circuit failures like open loop and overcurrent of the main switch are effectively controlled. A smart Auto Restart Timer (ART) function is built in to guarantee an automatic application recover, without any loss of reliability. |

ILPS22QSDual full-scale, 1260 hPa and 4060 hPa, absolute digital output barometer with embedded Qvar electrostatic sensor | Pressure Sensors, Transducers | 1 | Active | The ILPS22QS is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer, supporting dual full-scale up to user-selectable 4060 hPa. The device delivers ultra-low pressure noise with very low power consumption and operates over an extended temperature range from -40 °C to +105 °C.
The ILPS22QS comprises a sensing element and an IC interface which communicates over I²C, MIPI I3CSMor SPI interfaces from the sensing element to the application and supports 1.2 V digital interface as well. The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST.
The ILPS22QS embeds an analog hub sensing functionality which is able to connect an analog input and convert it to a digital signal for embedded processing. In addition, an embedded Qvar (electric charge variation detection) channel can be enabled for sensing in applications such as water leakage detection, tap, double tap, long press, and L/R - R/L swipe.
The ILPS22QS is available in a full-mold, holed LGA package (HLGA). The package is holed to allow external pressure to reach the sensing element. |
