描述

The EVAL-L9960 and EVAL-L9960T are the simplest solution to evaluate respectively the L9960 and L9960T functionalities providing all the inputs and outputs capabilities necessary to drive DC motors and monitor diagnostic functions.

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 condition, 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 through embedded application examples
The board is compatible with both 5V and 3.3V control systems.
