2.0, 7/2006 Quad H-Bridge Micromotor Driver with DC/DC Boost Converter The 17550 is a monolithic quad H-Bridge power IC ideal for portable electronic applications containing tiny bipolar stepper motors and/or brush DC-motors powered by two-to-four cell NiCd/NiMH batteries.

The 17550 operates from 2.5 V to 5.5 V, with independent control of each H-Bridge via parallel 3.0 V or 5.0 V logic-compatible I

17550 Features

* an on-board DC / DC boost converter that allows motor operation all the way down to 1.6 V (the boost converter supplies the gate-drive voltage for each of the four independent H-bridge output stages). Each output bridge has its own gate-drive and logic circuitry with built-in shoot-through current p
