MAX14919/MAX14919A Industrial-Protected, Quad-Channel, Low-Side Switch General Description Benefits and Features The MAX14919/MAX14919A industrial-protected quad- 5V or 7V to 60V Supply Voltage channel low-side switch features 140m (typ) on-resis- 800mA Load Current per OUT tance (R ) per channel with integrated 1kV/42 surge Integrated 5V/30mA Linear Regulator ON protection for robust operation. Logic Supply Input from 1.62V(min) to 5.5V(max) 5V to 48V Load Voltage Range Resistor-settable accurate current limiting provides guar- Up to 200kHz (min) Switching Rates anteed operating currents in the range of 100mA to 2x Inrush Load Current Option for 10ms 800mA. Loads that draw large activation or inrush currents Reduces Power and Heat Dissipation are supported using the 2x inrush load-current option. The 140m (typ) On-Resistance per channel outputs can be connected in parallel to achieve higher 1.7mA (typ) Supply Current load currents. The four switches are pin-controlled to allow Settable Load Current Limit for simple and fast switching of up to 200kHz. Robust Design Features The MAX14919/MAX14919A feature reverse current de- Internal inductive Energy Clamp at 55V(typ) tection. The MAX14919 implements reverse-current pro- Short-Circuit Protection tection by driving an external FET for non-capacitive Reverse Current Detection against Load-Supply loads. The MAX14919A has reverse current indication. Miswiring Inductive loads are turned off rapidly using the internal 1kV/42, 8s/20s Surge Protection high-voltage clamps. The switches are short-circuit and 8kV Contact and 25kV Airgap ESD Protection overload protected. -40C to +125C Operating Ambient Temperature The MAX14919/MAX14919A quad low-side switch is FAULT Indication for: available in a 6.5mm x 6.4mm footprint 20-TSSOP pack- Thermal Overload age and a 4mm x 5mm footprint 20-TQFN package spec- Reverse Load Current Detection ified over the -40C to +125C operating temperature Undervoltage Lockout on V Supply 5 range.
