Analog Devices Inc. MAX14919 Quad-Channel Low Side Switch

Analog Devices MAX14919 Quad-Channel Low Side Switch is an industrial-protected switch that features 140mΩ on-resistance (RON) per channel with integrated ±1kV/42Ω surge protection for robust operation. This quad-channel switch is pin-controlled, allowing for simple and fast switching of up to 200kHz. The MAX14919 switch features reverse-current detection to prevent damage against load supply miswiring faults. This low-side switch operates from a 5V or 7V to 60V supply voltage range and -40°C to +125°C operating temperature range. The Analog Devices MAX14919 Quad-Channel Low Side Switch is available in a 6.5mm x 6.4mm footprint, 20-TSSOP package. This switch IC is short-circuited and overload-protected. Applications include PLC/DCS systems, relay/solenoid drivers, motor control, and industrial digital outputs.
