MILPITAS, Calif., April 7, 2014 (GLOBE NEWSWIRE) -- Intersil Corporation (Nasdaq:ISIL), a leading provider of innovative power management and precision analog solutions, today announced the industry's first small form factor half-/full-bridge drivers that significantly extend power usage and overall product life of multi-cell lithium ion (Li) battery devices operating from 5V to 50V. The new HIP2103 and HIP2104 bridge drivers have a configurable topology to enable half-bridge, full-bridge and three phase motor-driven applications. They provide an innovative safety feature that prevents voltage kickback, which is the leading cause of damage and deterioration of Li batteries. The HIP2103/04 bridge drivers extend battery life through a unique power management method enabling the industry's lowest sleep mode current to minimize power consumption when the device is not in use or in stand-by mode. In addition, the HIP2104 includes integrated Linear Regulator LDOs to enable direct bias from the battery and an integrated bootstrap FET, which eliminates the need for external diodes.

From portable medical equipment to hand-held power tools to home automation products, end users demand products that have a long battery life, are reliable and last a long time. The new HIP2103/04 bridge drivers were specifically designed for these types of battery powered applications in which battery life, longevity and high reliability are required.
Intersil's battery consumption benefits are based on a unique control method that enables the HIP2103/04 bridge drivers to operate at <8uA low sleep mode current. This eliminates the need for a disconnect switch to maintain idle battery life when a device is not being used, extending the battery life. The proprietary sleep mode activation also eliminates the need for additional I/O control pins further simplifying the design.
To enable product robustness, the HIP2103/4 bridge drivers use Intersil's bridge phase node pin to withstand negative voltage transients up to -10V without duration constraints, preventing kickback voltage. This feature eliminates the need for voltage clamping circuits, effectively acting as a safety mechanism to prevent damage to the product and prolong its lifespan.
The HIP2104 bridge driver integrates two linear regulators for external loads, the boot strap FET and switch debouncer on VDen and VCen to minimize the number of external components required. The high level of integration reduces the bill of materials (BOM) and solution footprint while simplifying design and power-up sequencing. Size reduction is further accomplished by utilizing extremely small 3x3 and 4x4 thin dual flat no leads (TDFN) packages.
"The HIP2103/4 bridge drivers leverage our expansive portfolio of proprietary power management IP to deliver the long battery life and reliability required for motor-driven applications," said Mark Downing, senior vice president of Infrastructure and Industrial Power Products at Intersil. "With the new bridge drivers, we are delivering a uniquely designed solution that features the lowest quiescent current and lowest current sleep mode to dramatically extend the battery life of battery-powered devices."
