Functional Description and Electrical Characteristics
Note: The listed characteristics are ensured over the operating range of the integrated circuit.
Typical characteristics specify mean values expected over the production spread. If not otherwise specified,
typical characteristics apply at TA = 25
oC and the given supply voltage.
5.1
Supply and Reference
The device includes a power-on reset circuit. This feature will disable the channels and reset the internal registers
to their default values when the voltage on V5A1, V5A2, V5A3, and/or V5D are below their respective reset
thresholds.
The V5D pin and GND_D pin are the supply and ground pins for the digital circuit blocks. The current through these
pins contain high frequency components. Decoupling with ceramic capacitors and careful PCB layout are required
to obtain good EMC performance.
The V5A1, V5A2, V5A3 pins and GND_A pin are the supply and ground pins for the analog circuit blocks.
The V_SIGNAL pin supplies the SPI output pin (SO) and is the source voltage for the pull up currents on the CS_B
and RESET_B pins. V_SIGNAL should be connected to the I/O supply of the microcontroller (3.3V or 5.0V).
The BAT pin is an input pin used to detect over voltage faults. This pin is not a power supply input. A series resistor
should be connected between this pin and the solenoid supply voltage for transient protection.
Electrical Characteristics:
V5D = 4.75V to 5.25V, Vbat = 5.5V to 42V,
T
j = -40 °C to +150 °C, all voltages with respect to ground, positive
current flowing into pin (unless otherwise specified)
