MAX14919 Industrial-Protected Quad-Channel Low-Side Switch
The MAX14919 industrial-protected quad-channel lowside switch features140mΩ (typ) on-resistance (RON) per channel with integrated ±1kV/42Ω surge protection for robust operation.
Resistor-settable accurate current limiting provides guaranteed operating currents in the range of 100mA to 800mA. Loads that draw large activation or inrush currents are supported using the 2x inrush load-current option. The outputs can be connected in parallel to achieve higher load currents. The four switches are pin-controlled to allow for simple and fast switching of up to 200kHz
TMAX14919 features reverse-current detection to prevent damage against load-supply miswiring faults. This feature is disabled in MAX14919A.
Inductive loads are turned off rapidly using the internal high-voltage clamps. The switches are short-circuit and overload protected.
The MAX14919 quad low-side switch is available in a 6.5mm x 6.4mm footprint, 20-TSSOP package and is specified over the -40°C to +125°C operating temperature range.

MAX22007 Four-Channel 12-Bit Configurable Analog Output with Integrated Voltage Reference
The MAX22007 is a software-configurable four-channel analog output device that drives a voltage or current output on each channel. All outputs are protected to ±42VP-P for high-voltage supply of HVDD = 8V to 20V and HVSS = -2V to 0V.
Each output channel of the MAX22007 features a 12-bit DAC with fast settling time using a shared internal voltage reference. The device offers low-offset, high-voltage amplifiers to condition the signal from low-voltage DAC outputs to high-voltage or current outputs. If one output is miswired, all other outputs remain unaffected and function normally. For each channel, an internal comparator can be used to determine the load impedance and allows the microcontroller to intelligently select for voltage or current output mode. All outputs are kept safe by integrated current protection for functional and thermal robustness. The MAX22007 also includes a thermal shutdown circuit that protects the device when the junction temperature exceeds 165°C (typ).
The MAX22007 communicates with a microcontroller using a SPI interface at clock rates up to 30MHz with an optional eight-bit CRC for improved data integrity. Eight GPIOs can be used to interface and control other resources in the application circuit. The MAX22007 operates from a 2.7V to 5.5V VDD low-voltage supply and an 8V to 24V HVDD positive high-voltage supply. The negative voltage supply HVSS can be set between -2V and 0V.
