Dialog adds ARM multicore support to PMICs

LONDON – Dialog Semiconductor plc has launched two power management ICs (PMICs) for tablet PCs, smartphones, embedded computers and multimedia players.

The DA9053 and DA9021 devices support mobile graphics and application processor families. The DA9053 is intended for high-end multicore-based applications and supports the ARM Cortex family whilst the DA9021 addresses lower power cost-sensitive applications.

The DA9053 combines a 1.8-A rated dual-input DC/USB power path router with a switching battery charger and includes support for multiple external memory configurations. The DA9053 is suitable for portable media and wireless computing applications, such as tablet PCs, Dialog said.

The DA9021 delivers the same highly power-up sequencing and has been retargeted to be suitable for lower power single processor core portable consumer markets, such as e-readers and DAB receivers. It includes a 1.3-A single input USB charger and its internal regulators deliver approximately half the total current relative to DA9053.

"Dialog's latest generation PMICs extend the company's leadership in configurable system power management via multicore support," said Udo Kratz vice president and general manager of Dialog's audio and power management business unit, in a statement.

The DA9053 is supplied in a 169 ball VFBGA 7-mm by 7-mm package with 0.5-mm pin pitch or VFBGA 11-mm by 11-mm package with 0.8-mm pitch and is available in both consumer and automotive grades. The DA9021 is supplied in a 64 ball 4-mm by 4-mm wafer-level package with 0.5-mm pitch. Samples of both the DA9053 and the DA9021 are available immediately.

Companies supported by Dialog include: Freescale, Marvell, Renesas and Samsung.
