Overview
The LX8237 integrated power management IC is the ideal choice for next generation enterprise HDD and SSD power systems. It consists of 5V and 12V eFuse over-voltage protection switches and 3.3V and 0.94V switching regulators. The 5V and 12V eFuse switches are designed for hot swap and limit inrush current limiting. In addition, they provide fast acting protection of voltage surges, output over current, and crow bar events. Under an input voltage surge condition, the E-Fuse devices clamp the output voltage to protect downstream circuitry and maximize run time. In addition to surge protection, The 5V eFuse switch provides bidirectional voltage blocking to block current in the reverse direction under input voltage crowbar conditions. Both E-Fuses have thermal protection to protect all circuitry in the event of sustained surge or short conditions. The LX8237 has dual current monitoring outputs to allow monitoring of the input power under all conditions. Both the 5V and 12V inputs are monitored.
