| Integrated Circuits (ICs) | 2 | Active | The device is an integrated H-Bridge for resistive and inductive loads for automotive applications. Target application includes throttle control actuators, exhaust gas recirculation control valves and general purpose DC motors such as turbo, flap control and electric pumps.
The driving strategy is enhanced by configurable PWM / DIR pins and IN1/IN2.
The H-Bridge contains integrated free-wheel diodes. In case of freewheeling condition, the low-side only is switched on in parallel of its diode to reduce power dissipation.
The integrated Serial Peripheral Interface (SPI) makes it possible to adjust device parameters, to control all operating modes and read out diagnostic information. |

L9963EAutomotive chip for battery management applications with daisy chain up to 31 devices | Power Management (PMIC) | 1 | Active | The L9963E is a Li-ion battery monitoring and protecting chip for high-reliability automotive applications and energy storage systems. Up to 14 stacked battery cells can be monitored to meet the requirements of 48 V and higher voltage systems.
Each cell voltage is measured with high accuracy, as well as the current for the on-chip coulomb counting. The device can monitor up to 7 NTCs. The information is transmitted through SPI communication or isolated interface.
Multiple L9963E can be connected in a daisy chain and communicate with one host processor via the transformer isolated interfaces, featuring high-speed, low EMI, long distance, and reliable data transmission.
Passive balancing with programmable channel selection is offered in both normal and low power mode (silent balance). The balancing can be terminated automatically based on internal timer interrupt. Nine GPIOs are integrated for external monitoring and control. The L9963E features a comprehensive set of fault detection and notification functions to meet the safety standard requirements. |
L9963TAutomotive general purpose SPI to isolated SPI transceiver | Integrated Circuits (ICs) | 2 | Active | L9963T is a general purpose SPI to isolated SPI transceiver intended to create a communication bridge between devices located into different voltage domains.
L9963T is able to transfer communication data incoming from a classical 4-wire based SPI interface to a 2-wire isolated interface (and viceversa).
The transceiver supports both transformer and capacitive isolation, since the isolated signal generated according to a proprietary protocol is suitable to be transmitted over both decoupling circuitries.
The device can be configured either as Slave or as Master of the SPI bus and supports any protocol made of SPI frames 8 to 64 bit long. The transceiver manages the transfer of the information without performing any protocol check.
SPI peripheral can work up to 10 MHz when configured as Slave. SPI clock frequency can be programmed among (250 kHz; 1 MHz; 4 MHz; 8 MHz) when configured as Master.
Isolated SPI peripheral features two different operating modes: slow @333 kbps and fast @2.66 Mbps.
The asynchronicity between the two sides is internally managed, allowing all possible configuration frequencies on both peripherals to be used in application.
L9963T features an internal queue of 3 slots for the frames received on the SPI port and a queue of 20 slots for the ones received on the isolated SPI side. This allows buffering and decoupling the two different clock domains.
The device is natively compatible with L9963 isolated SPI, allowing its usage in the BMS applications.
L9963T is compatible with both 3.3 V and 5 V logics. |
