Описание

The L9958XP is a SPI-controlled H-bridge Driver designed for the control of DC and stepper motors in safety critical applications and under extreme environmental conditions. The H-bridge is protected against over-temperature, short-circuits and has an under-voltage lockout for all the supply voltages Vs and Vdd and for over-voltage on Vdd. All malfunctions causes the output stages to go tristate. 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. Current regulation threshold can be set by SPI from 2.5 to 8.6A (typical), in 4 steps. Guaranteed accuracy is ±10% on all temperature range, using an external reference resistor with 1% accuracy over all temp range. Current limitation threshold is linearly reduced by temperature over 165°C and a thermal warning bit is set by SPI.

• All pins withstand 19V, Vs and output pins withstand 40V
• Full path Ron from 100 (at Tj=-40°C) to 300mR (at Tj=150°C)
• Logic inputs TTL/CMOS-compatible
• Operating frequency up to 20kHz
• 16-bit SPI interface for configuration/diagnostics, daisy chain capability
• Over-temperature and short-circuit protection
• VS under-voltage disable function
• VDD under-voltage and over-voltage protection
• VDD over-voltage detection
• Open-load detection in on condition
• Full diagnostics in OFF-state
• Enable and disable input
• Low standby current (<10µA)
• Voltage and current slew-rate control for low EMI, programmable through SPI
• 4 to 28V Operating battery supply voltage
