ET3148A Description

Short technical summary and product information.

The ET3148A is an advanced load management switch from ETEK Microelectronics, designed for applications requiring integrated power control. It operates within a wide input voltage range of 1.5V to 6.0V DC, making it suitable for various consumer, portable, and industrial devices.

This load switch features a low-impedance MOSFET with a typical on-resistance as low as 21mΩ at 5.5V. It includes slew-rate control to prevent inrush current and excessive voltage droop during turn-on. A key feature is the True Reverse Current Blocking (TRCB) function, which prevents unwanted current flow from VOUT to VIN in both ON and OFF states.

The ET3148A boasts exceptionally low off-state current drain, less than 1uA maximum, facilitating compliance with stringent standby power requirements. The switch is controlled by a logic input that is active HIGH, capable of interfacing directly with low-voltage control signals. It is ESD protected, rated above 8kV HBM and 1.5kV CDM.

Packaged in a compact WLCSP6 (1.56mm x 1.06mm) with a 0.5mm pitch, the ET3148A is designed for space-constrained applications. Its applications include smartphones, tablet PCs, HDD, storage devices, portable media players, laptops, industrial handheld equipment, and enterprise systems.
