Renesas DA9063-XXHO1

Overview

DA9063-XXHO1 from Renesas Electronics is a high-current system PMIC designed for dual- and quad-core processors in smartphones, tablets, ultrabooks, and automotive infotainment systems. It integrates six DC-DC buck converters (up to 2.5 A each), eleven programmable LDOs (up to 300 mA), a 10-channel 10-bit ADC, RGB-LED drivers, and PWM-controlled vibration motor driver - all supporting core supply up to 5 A and operating from –40 °C to +125 °C.

For engineers reviewing the DA9063-XXHO1 datasheet, DA9063-XXHO1 pinout, DA9063-XXHO1 application, or DA9063-XXHO1 equivalent, key selection criteria include its dual-phase 5 A core supply capability, OTP-programmable power sequencing, ultra-low 1.5 µA RTC mode, AEC-Q100 Grade 2 qualification (for DA9063-A variant), and support for DDR memory termination and remote capacitor LDO placement.

Technical Context

The DA9063-XXHO1 implements a hardware-based OTP start-up sequencer with autonomous power-on-reset and software-configurable slot delays, enabling deterministic boot across mobile and automotive platforms. Its six buck converters operate at 3 MHz (±10%) with automatic sleep mode and pin/software-controlled Dynamic Voltage Control (DVC) for adaptive processor voltage scaling.

It features two independent control interfaces (4-wire and HS 2-wire), a 10-bit ADC with programmable thresholds and internal current source for resistive sensing, and rail switch controllers for fast power domain isolation. The integrated 32 kHz oscillator supports crystal frequency adjustment, and LDO8 is configurable as a 6-bit PWM vibration motor driver with battery voltage correction.

FAQ

What is the maximum continuous output current supported by DA9063-XXHO1 for processor core rails?

DA9063-XXHO1 supports up to 5 A continuous core supply using dual-phase operation of BuckCore1 and BuckCore2. Each buck delivers 2.5 A, and in merged mode they combine to provide 5 A at 0.3–1.4 V with dynamic voltage control - verified in the datasheet's Electrical Characteristics section (Rev 2.4, p.44–46). This capability is essential for powering modern ARM Cortex-A series SoCs in DA9063-XXHO1-based designs.

Does DA9063-XXHO1 support DDR memory bus termination, and if so, which buck provides it?

Yes, DA9063-XXHO1 supports DDR memory bus termination via BuckPro, which can be configured to deliver programmable termination voltages between 0.6 V and 0.9 V. This function is explicitly documented in Section 6.10.3 ("BUCKPRO in DDR Memory Bus Termination Mode") of the datasheet (Rev 2.4, p.106). DA9063-XXHO1's BuckPro maintains fast transient response required for LPDDR3/LPDDR4 interfaces without external components.

What is the RTC quiescent current of DA9063-XXHO1, and how is it achieved?

DA9063-XXHO1 achieves 1.5 µA RTC quiescent current in RTC mode, as specified in Section 5.3 ("Typical Current Consumption") of the datasheet (Rev 2.4, p.20). This ultra-low value results from dedicated low-leakage circuitry, crystal oscillator optimization, and isolated RTC power domain - enabling multi-year operation on coin-cell backup in DA9063-XXHO1 automotive and portable applications.

How many GPIO pins does DA9063-XXHO1 offer, and what are their key configurable functions?

DA9063-XXHO1 provides up to 16 freely configurable GPIO pins, as confirmed in Section 1 ("Key Features") and Section 6.7 ("GPIO Extender") of the datasheet (Rev 2.4, pp.2, 85–88). These pins support keypad supervision, application wake-up, timing-controlled external regulator enable, and peripheral power switching - all programmable via register map pages 0 and 1. Each GPIO in DA9063-XXHO1 can be individually assigned direction, pull-up/down, and interrupt behavior.

Is DA9063-XXHO1 qualified for automotive applications, and what is its AEC-Q100 grade?

DA9063-XXHO1 itself is not AEC-Q100 qualified; however, the DA9063-A variant - part of the same family - is explicitly rated for AEC-Q100 Grade 2 (–40 °C to +105 °C ambient, +125 °C junction), as stated in the "Key Features" section (Rev 2.4, p.2). While DA9063-XXHO1 shares identical electrical and thermal specifications, users requiring automotive qualification must select the DA9063-A variant. All DA9063-XXHO1 design resources apply directly to DA9063-A.
