Frequently Asked Questions
How precise is the current measurement on PINA239AQDGSRQ1 and what shunt resistor range does it support?
PINA239AQDGSRQ1 uses a 16-bit ADC for current sensing, achieving precision below 0.1% full-scale error across the measurement range. It supports external shunt resistors sized for the target current range, accommodating bus currents from milliamperes to tens of amperes within the 85 V maximum bus voltage limit.
What automotive qualification does PINA239AQDGSRQ1 carry and which temperature range does it cover?
PINA239AQDGSRQ1 is AEC-Q100 Grade 1 qualified, covering an operating temperature range of -40°C to +125°C, making it suitable for under-hood automotive applications experiencing wide thermal cycling over the vehicle lifetime.
Which communication interface does PINA239AQDGSRQ1 use and how fast can a host MCU read power data?
PINA239AQDGSRQ1 uses an SPI interface, enabling data transfers at clock rates up to several MHz so that a host microcontroller can read current, voltage, and calculated power registers within microseconds, supporting real-time control loops in automotive power management systems.
For a 48 V automotive DC-DC converter design, how does PINA239AQDGSRQ1 fit into the monitoring architecture?
With an 85 V maximum bus rating, PINA239AQDGSRQ1 safely monitors 48 V nominal rails including transient spikes. Its 16-bit resolution and SPI output allow the system ECU to log power efficiency data across load ranges from 1 A to over 20 A with sub-1% measurement uncertainty.
