What are the key features of PTPS65917ATRGZRQ1?
- Integrated multi-rail power management with programmable DC-DC buck converters delivering adjustable outputs from 0.9 V for processor core and I/O supplies
- AEC-Q100 automotive qualification enabling use in ADAS, infotainment, and gateway ECU designs over -40°C to 125°C
- I2C-controlled rail sequencing and voltage scaling supporting dynamic voltage and frequency scaling (DVFS) for automotive SoC power optimization
What is PTPS65917ATRGZRQ1 used for?
The PTPS65917ATRGZRQ1 is designed for automotive infotainment, ADAS domain controllers, and digital cockpit platforms where a single PMIC must supply multiple processor rails at precisely sequenced voltages starting from 0.9 V. Its I2C programmability allows software-controlled DVFS to reduce power consumption during low-load operating states in gateway ECUs. The AEC-Q100 qualification and QFN package meet the reliability and space requirements of under-dashboard automotive electronic control units operating at up to 125°C.

Frequently Asked Questions
What makes PTPS65917ATRGZRQ1 suitable for automotive ADAS and infotainment processor power supply designs?
The PTPS65917ATRGZRQ1 is AEC-Q100 qualified and operates from -40°C to 125°C, meeting automotive thermal reliability standards. It integrates multiple programmable buck DC-DC converters with outputs as low as 0.9 V, supplying the processor core, memory, and I/O rails from a single compact QFN device, which reduces BOM count by replacing 4 to 6 discrete regulators.
How does I2C voltage scaling on PTPS65917ATRGZRQ1 help reduce power consumption in an automotive gateway ECU?
Through its I2C interface, the host processor can dynamically adjust buck converter output voltages in fine steps down to 0.9 V to implement dynamic voltage and frequency scaling. During low-activity states, lowering the core supply voltage by 200 mV to 300 mV can reduce processor power dissipation by 30% to 50%, extending thermal headroom and reducing cooling requirements in sealed automotive enclosures.
Can PTPS65917ATRGZRQ1 handle the sequenced power-up required by modern automotive SoCs with multiple voltage domains?
Yes. The device supports programmable power-up and power-down sequencing across its output rails, ensuring each voltage domain reaches its target within a controlled time window. This prevents latch-up and undefined logic states during boot on automotive SoCs that require DDR memory rails to come up before core rails settle to their nominal 0.9 V to 1.2 V levels.
