U6815BM Datasheet | Atmel

Features - Six high-side and six low-side drivers - Outputs freely configurable as switch, half bridge, or H-bridge - Capable to switch all kinds of loads such as DC motors, bulbs, resistors, capacitors and inductors - 0.6A continuous current per switch - Low-side: RDSon < 1.5Ω versus total temperature range - High-side: RDSon < 2.0Ω versus total temperature range - Very low quiescent current IS < 20µA in Standby Mode - Outputs short-circuit protected - Overtemperature prewarning and protection - Under- and overvoltage protection - Various diagnosis functions such as shorted output, open load, overtemperature and power supply fail - Serial data interface - Daisy chaining possible - SO28 power package Description The Atmel® U6815BM is a fully protected driver interface designed in 0.8-µm BCDMOS technology. It is used to control up to 12 different loads by a microcontroller in automotive and industrial applications. Each of the 6 high-side and 6 low-side drivers is capable of driving currents up to 600m A. The drivers are freely configurable and can be controlled separately from a standard serial data interface. Therefore, all kinds of loads such as bulbs, resistors, capacitors, and inductors can be bined. The IC design especially supports the applications of H-bridges to drive DC motors. Protection is guaranteed for short-circuit conditions, overtemperature, under- and overvoltage. Various diagnostic functions and a very low quiescent current in standby mode enable a wide range of applications. The U6815BM has automotive qualification for conducted interferences, EMC protection, and 2-k V ESD protection. 4545E- AUTO- 06/12 Figure 1.
