IC Integrated Circuits A4911KJPTR-T-1 LQFP-48 Ignition Controllers

Description:

The A4911/13/16 product family provides six high current gate drives capable of driving a wide range of Nchannel power MOSFETs. The gate drives are configured as three half bridges, each with a high-side drive and a low-side drive. The three half bridges can be operated independently or together as a three-phase bridge driver for BLDC or PMSM motors. For maximum flexibility, the 491x product family provides a serial interface (SPI) to alter programmable bridge settings and read back detailed diagnostic and verification information. In the addition, the A4911 and A4913 include three low-side current sense amplifiers with programmable gain and offset. The amplifiers are specifically designed for current sensing in the presence of high voltage and current transients. These amplifiers can be used independently to provide low-side current sensing in three phases or can be used together to provide redundant current sensing. Several package options are available including a Leaded Quad Flat Pack (LQFP) – 48 and a Leadless Quad Flat Pack (QFN – 48). The A4911/13/16 devices are BLDC MOSFET drivers specifically designed for safety critical automotive systems, such as Electronic Power Steering (EPS) and Fans and Blowers. The extensive diagnostics and verification features coupled with ISO-26262 development standard enable end users to achieve ASIL-D certification. Several package options are possible, available now are a Leaded Quad Flat Pack (LQFP) – 48 and a Leadless Quad Flat Pack (QFN – 48). Exposed pad for improved thermal performance.
