The MAX14919/MAX14919A industrial-protected quad-channel lowside switch features 140mΩ (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 500kHz. The MAX14919/MAX14919A features reverse current detection. The MAX14919 implements reverse-current protection by driving an external FET for non-capacitive loads. The MAX14919A has reverse current indication. Inductive loads are turned off rapidly using the internal high-voltage clamps. The switches are short-circuit and overload protected. The MAX14919/MAX14919A quad low-side switch is available in a 6.5mm x 6.4mm footprint, 20-TSSOP package and a 4mm x 5mm footprint 20-TQFN package specified over the -40°C to +125°C operating temperature range.
