EVAL-L9960/L9960T
Introduction
The EVAL-L9960 and EVAL-L9960T are evaluation boards designed to provide the user a
platform for the L9960 and L9960T, that are integrated H-Bridge (Twin for L9960T) for
resistive and inductive loads for automotive applications, such as throttle control actuators
or exhaust gas recirculation control valves.
The board offers all the main input/output capabilities needed to drive a DC motor properly
and to provide diagnostic functionalities.
Full diagnostic is available through SPI. By using SPI communication, it is possible to
program L9960 and L9960T while the application is running (e.i. set the current limitation).
A dedicated pin array allows connecting easily a SPC5 discovery+ board and the EVAL-
L9960/L9960T. In association with the discovery board SPC560P-DISP a dedicated SW
allows controlling a motor control application by using a PC via a USB port.
The device is an integrated H-Bridge for resistive and inductive loads for automotive
applications, such as throttle control actuators or exhaust gas recirculation control valves.
The driving strategy is enhanced by configurable PWM / DIR pins as IN1/IN2.The H-Bridge
contains integrated free-wheel diodes. In case of freewheeling conditions, the low side or
the high side transistor is switched on in parallel of its diode to reduce power dissipation.
The integrated Serial Peripheral Interface (SPI) allows device parameters adjustment and to
control all operating modes and read out diagnostic information.
Detailed failure diagnostics on each channel is provided via SPI: short circuit to battery,
short circuit to ground, short circuit overload, over temperature. Open-load can be detected
in ON condition, for the widest application ranges.
The EVAL-L9960 and EVAL-L9960T boards are suitable for both beginners and expert
users working in standalone mode connected with any control system or combined with all
SPC5 Discovery+ boards through a computer graphic interface or though embedded
application examples.
The board is compatible with both 5V and 3.3V control systems
