Product details
Overview
DA9063-A0HO2 from Renesas Electronics is a high-current system PMIC designed for dual- and quad-core processors in mobile and automotive applications, delivering up to 5 A core supply, integrating six DC-DC buck converters (total 12 A continuous), eleven programmable LDOs (up to 300 mA), and a 10-bit ADC with nine channels - used in car infotainment, ADAS, and ultra-books.
For engineers reviewing the DA9063-A0HO2 datasheet, DA9063-A0HO2 pinout, DA9063-A0HO2 application, or DA9063-A0HO2 equivalent, key selection considerations include its AEC-Q100 Grade 2 qualification, dual-phase 5 A core supply capability, OTP-programmable power sequencing, and support for DDR memory termination mode on BUCKPRO.
Technical Context
The DA9063-A0HO2 implements a hardware-based OTP start-up sequencer enabling autonomous system boot without host intervention, and supports two independent control interfaces: HS-2-WIRE (I²C-compatible) and 4-WIRE (SPI-like) for flexible host integration. Its power manager handles five ultra-low-power modes (<20 µA), including a 1.5 µA RTC mode with alarm and crystal frequency adjustment.
Buck regulation uses fixed 3 MHz switching (±10%) to enable compact 1 µH inductors; DVC is implemented on four LDOs and three bucks (BUCKCORE1/2, BUCKPRO) for dynamic processor voltage scaling. The integrated rail switch controller provides fast domain isolation with current-limited external peripheral switching.

FAQ
What is the AEC-Q100 qualification status of DA9063-A0HO2?
The DA9063-A0HO2 is fully qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient / −40 °C to +125 °C junction), with test reports covering HTOL, TC, UHAST, ESD, and AC/DC stress. This qualification applies specifically to the A0HO2 variant and confirms suitability for automotive infotainment and ADAS applications outside the engine compartment.
Does DA9063-A0HO2 support hardware-only power sequencing without host processor involvement?
Yes, DA9063-A0HO2 integrates an OTP-programmable power sequencer that executes autonomous start-up and shut-down sequences directly from on-chip memory. This eliminates dependency on host firmware during cold boot or reset recovery - a critical feature for automotive systems requiring deterministic power behavior.
Can DA9063-A0HO2 supply DDR memory termination voltage, and which buck channel provides it?
Yes, DA9063-A0HO2 supports DDR memory bus termination mode on BUCKPRO, configurable via register settings to deliver a precise, low-noise 0.6 V to 1.2 V output with fast transient response - validated for LPDDR3 and LPDDR4 interfaces in automotive head units.
How many GPIOs does DA9063-A0HO2 offer, and what are their key configurable functions?
DA9063-A0HO2 provides up to 16 freely configurable GPIO pins supporting keypad supervision, application wake-up, timing-controlled enable signals for external regulators or power switches, and general-purpose digital I/O - all programmable via I²C or SPI interface with interrupt capability.
What is the minimum supply current of DA9063-A0HO2 in RTC-only mode, and how is backup maintained?
DA9063-A0HO2 draws just 1.5 µA in RTC mode, enabling multi-year operation from a CR2032 coin cell.
