Load Switch Delivers 7 A Continuous

Micrel, Inc. introduced the MIC95410 7 A load switch in a compact 1.2 mm x 2.0 mm package. This device can be used for systems requiring power partitioning and has the capability of a controlled power up sequence with ramp control, a feature often needed in applications such as industrial computing, server boards, medical devices, tablets, notebooks, and solid state drives. The MIC95410 is available in volume quantity with 1,000 quantities pricing starting at $0.45.

This device operates from a 2.7 V to 9 V bus rail and can switch on a load voltage from 0.5 V to 5.5 V. The extremely low 6.6 mW ON resistance of the integrated FET minimizes power dissipation and reduces voltage drop across the switch thereby allowing for greater voltage accuracy to the circuit downstream, especially critical in low voltage applications. Other features include a control input for sequencing and an optional capacitor that allows the user to adjust the output slew rate. The MIC95410 is fully specified from -40 °C to +12 5°C.
