1Overview
1.1 Features
• Two Fully Independent Channels
• Integrated N-channel DMOS transistors
• Programmable Average Current with 10-bit resolution
via SPI
– I
avg
range = 0 to 1000 mA (typical)
• Programmable Superimposed Dither
– Programmable Frequency (41 Hz to 1 kHz typ)
– Programmable Amplitude (12.5 to 390 mVpp typ)
– Programmable Hysteresis (40 to 110 mVpp typ)
• Interface and Control
– 16-bit SPI (Serial Peripheral Interface) daisy chainable
– A single “Default” pin to disable both channels and reset the programmable
registers of both channels
– 5.0 V and 3.3 V logic compatible I/O
– The contents of all registers can be verified via SPI
– Operation with or without external reference possible
• Protection
– Overcurrent
–Overvoltage
– Overtemperature
• Diagnostics
– Overcurrent / shorted solenoid
– Overtemperature
– Open load
– Short to GND
• Green Product (RoHS compliant)
• AEC Qualified
