HIGH SIDE SWITCH WITH INPUT OVERVOLTAGE AND OVERCURRENT PROTECTION

HIGH SIDE SWITCH WITH INPUT OVERVOLTAGE AND OVERCURRENT PROTECTION

The project here is a 48V protected, high side switch designed to switch a 5A output load from input voltages from 8V to 48V. The circuit helps the user to easily ON/OFF the high current and voltage load with over-voltage lockout and over-current protection. The wide input range and low shutdown current (1μA typical) make it suitable for automotive, industrial,

TEXAS INSTRUMENTS TMUX6219 SINGLE CHANNEL 2 1 SPDT SWITCH

TEXAS INSTRUMENTS TMUX6219 SINGLE CHANNEL 2:1 (SPDT) SWITCH

Texas Instruments TMUX6219 Single Channel 2:1 (SPDT) Switch is a complementary metal-oxide semiconductor (CMOS) switch in a single channel, 2:1 (SPDT) configuration. The device works with single supply (4.5V to 36V), dual supplies (±4.5V to ±18V), or asymmetric supplies (such as VDD = 8V, VSS = –12V). The TMUX6219 supports bidirectional analog and digital signals on the source (Sx)
