STPM801Hot Swap & Ideal Diode Controller for high redundancy power architectures | Integrated Circuits (ICs) | 1 | Active | STPM801 offers integrated hot swap, soft start and oring protections. It protects loads from high voltage transients, limiting and regulating the output during an overvoltage event, such as load dump, by controlling the voltage drop across an external N-channel MOSFET.
The STPM801 also monitors the input supply to protect in case of overvoltage (OV) and undervoltage (UV) conditions.
An integrated ideal diode controller drives a second MOSFET (the oring) to replace a Schottky diode for reverse input protection and output voltage holdup. The STPM801 controls the forward voltage drop across the MOSFET and minimizes reverse current transients in case of fault like power source failure, brownout or input short.
STPM801 offers a set of features to support applications that need to fulfill functional safety requirements as defined by automotive Safety Integrity Level (ASIL) A-B-C-D depending on application TSR. |
STPM802Synchronous Buck-Boost Controller | OR Controllers, Ideal Diodes | 1 | Active | The STPM802 is a synchronous 4-Switch single phase non inverting buck-boost DC/DC controller that regulates output voltage, from an input voltage above, below, or equal to the output voltage. It offers an adjustable fixed frequency operation and spread spectrum to reduce EMI emissions.
The IC provides inductor and output current monitor, OV/UV protections and Power Good flag. Fault protection is also provided to detect output short-circuit condition, during which the IC retries, latches off, or keeps running.
The IC implements a low power mode function in which control loop management changes in order to reduce power dissipation.

STPMC1Programmable poly-phase energy calculator IC | Integrated Circuits (ICs) | 1 | LTB | The STPMC1 device functions as an energy calculator and is an ASSP designed for effective energy measurement in power line systems utilizing Rogowski, current transformer, Shunt or Hall current sensors. Used in combination with one or more STPMSx ICs, it implements all the functions needed in a 1-, 2- or 3-phase energy meter. It can be coupled with a microprocessor for multi-function energy meters, or it can directly drive a stepper motor for a simple active energy meter. The calculator has five input data pins. The first three receive the voltage and current information of the phases. In fact, each data input processes two ΔΣ signals, multiplexed in time and generated by the STPMSx device. The fourth input receives multiplexed ΔΣ signals also, and can be used to sense the neutral current or another signal - temperature, for example. The fifth input data pin accepts non-multiplexed ΔΣ signals and it can be used for sensing the magnetic field information from a Hall sensor. Four internal hard-wired DSP (digital signal processing) units perform all the computations on the ΔΣ streams in real time by means of ΔΣ arithmetic blocks. This allows the achievement of very high computation precision with fast and efficient digital architecture. All the data recorded by the STPMC1 are accessible through an SPI port, which is also used to configure and calibrate the device. The configuration and calibration data can be saved in a 112-bit OTP block, or dynamically set in microprocessor-based meters. |

STPMIC25Highly integrated power management IC for microprocessor units | Integrated Circuits (ICs) | 3 | Active | The STPMIC25 is a fully integrated power management IC designed for the STM32MP2x MPU's family applications requiring low power and high efficiency.
The device integrates advanced low power features controlled by a host processor via I²C and IO interfaces.
The STPMIC25 regulators are designed to supply power to the application processor as well as to the external system peripherals such as: DDR, flash memories, and other system devices.
Seven buck SMPS are optimized to provide an excellent transient response and output voltage precision for a wide range of operating conditions. Very high efficiency in the full output load range is achieved due to low power mode (LPM) and high power mode (HPM) selection. All the buck converters are capable of a smooth transition from LPM to HPM. The converters use an advanced PWM phase shift synchronization technique with integrated PLL and a programmable spread spectrum frequency modulation to reduce EMI. |
STPMS1Smart sensor Dual channel 1st order ΣΔ modulator with embedded PGA | Integrated Circuits (ICs) | 1 | LTB | The STPMS1, also called a smart-sensor device, is an ASSP designed for effective measurement in power line systems utilizing the Rogowski coil, current transformer, or shunt principle. It is used in combination with the STPMC1 programmable poly-phase energy calculator IC, as a building block for single-phase or poly-phase energy meters. The STPMS1 is a mixed signal IC consisting of an analog and a digital section. The analog section consists of a pre-amplifier and two 1storder ΣΔ modulator blocks, band-gap voltage reference, a low-drop voltage regulator, and DC buffers, while the digital section consists of a clock generator and output multiplexer. This device is designed for use in medium resolution measurement applications when single or double inputs must be monitored at the same time. |
