Power management unit with configurable start-up sequences

austriamicrosystems has released the AS3607, a highly integrated power management IC (PMIC) that features a level of start-up sequence programmability not found in competing devices. Suitable for PNDs, PMPs, GPS devices, and PDAs, the PMIC touts software programmable start-up sequences, bringing flexibility to the market. The user can program the start-up sequence with timing steps of 1ms or 4ms, insuring that all ARM-based processors can easily be covered. To control other parts of the system, the general purpose I/O pins can be programmed to a specific timing.

The integrated DC/DC step-up converter is capable of generating voltages up to 30V to supply OLED displays or LEDs for backlighting LCD displays. In the case of LEDs two strings of up to 8 LEDs can be powered, whereas the current is programmable via registers in 150µA steps, enabling smooth dimming.
