L9396Automotive Multiple Power Supply IC | Integrated Circuits (ICs) | 1 | Active | The L9396 is an integrated power management System Basis Chip targeting a large spectrum of automotive electronics applications, in particular ABS, EPS and Transmission, compatible with single (12 V) battery system.
It combines a switched mode power supply for pre-regulation along with 3 independent integrated linear regulators and a powerful configurable regulator for µC supply that can operate either in buck or linear mode with an external FET.
The device also integrates a 4-channel flexible interface for Wheel Speed Sensor or tracking regulation, 2 configurable pre-drivers for fail safe and motor pump, 1 configurable general purpose outputs, wake-up detection circuitry, advanced fail-safe functionality, watchdog control and system monitoring.
The boost regulator (optionally enabled) is intended to sustain cold cranking pulses, stop & start and weak battery conditions, while the buck pre-regulator drastically improves the power efficiency and CO2 emissions.
Different combinations enable to supply the system microcontroller and external peripheral loads and sensors with wide current ranges and adjustable voltage levels.
In addition, the L9396 provides enhanced system standby functionalities. |
L93PIQuad Low Side Driver | Power Distribution Switches, Load Drivers | 1 | Active | The L93PI is a monolithic integrated quad low side driver realized in advanced Multipower-BCD technology. It is intended to drive lines, lamps or relais in automotive or industrial applications. |
L9409Alternator voltage regulator with load response control | Special Purpose Regulators | 1 | Obsolete | The L9409 is a monolithic multifunction alternator voltage regulator intended for use in automotive applications.
The device regulates the output of an automotive generator by controlling the field winding current by means of either an analog fixed frequency PWM signal or digital fixed frequency PWM signal (LRC). The Load Response Control function is activated in order to eliminate IC engine speed fluctuation and vibrations caused by the insertion of sudden electrical loads during alternator low speed operations (f < 310 Hz). Both the analog and digital duty cycle are applied to a high side driver.
The device is able to regulate the voltage either using a feedback signal from B pin or from S pin depending on application needs. S pin is intended to have a clear direct connection with the positive terminal of the car battery. If this connection gets lost the device will regulate voltage using B pin giving a fail safe functionality.
Using L pin is possible to sense key switch and a pre-excitation duty cycle is applied on the field coil in order to start phase voltage sensing. In the case L connection gets lost, device starts to generate using residual magnetism of the generator.
Field, lamp and relay drivers are protected against short circuit. |
