The ET3159 advanced load management switches target applications requiring a highly integrated solution. It disconnects loads powered from DC Power Rail (<6V) with stringent off-state current targets and high load capacitances (up to 200uF). Each switch consists of slew-rate controlled low-impedance MOSFET Switch and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush-current and the resulting excessive voltage droop on power rails.
The ET3159 has True Reverse Current Blocking (TRCB) function blocking unwanted reverse current from OUT to IN during ON/OFF state. These devices have exceptionally low off-state current drain (<1uA max) which facilitate compliance in very low stand-by power applications.. Switch control is managed by a logic input (Active HIGH) capable of interfacing directly with low voltage control signal/GPIO with no external pull-down resistor required,In ET3159, 90Ω on-chip load resistor is added for output quick discharge when switch is turned off (EN=0V).
ET3159 is offered DFN4(1.2×1.6) package, which is ideal for small form factor portable equipment .
