Key Features

  • AEC-Q100 screened automotive-grade transformer driver ensuring reliable isolated power conversion across harsh automotive environments
  • Low-noise 420 kHz fixed switching frequency minimizes EMI and simplifies input/output filter design in isolated DC-DC stages
  • 1 A peak drive capability supports a wide range of transformer sizes for flexible isolated power supply topologies
  • Wide 2.25 V to 5.5 V input supply range enables compatibility with 3.3 V and 5 V system rails in automotive ECUs

Applications

The XSN6505BQDBVTQ1 is used in automotive ECUs, CAN/LIN transceiver modules, and sensor nodes that require a compact isolated power supply for bus-side circuitry. Its low-noise 420 kHz operation and 1 A drive capability make it ideal for push-pull or half-bridge transformer driver stages in galvanically isolated designs. The tiny 6-pin SOT-23 footprint allows integration into space-constrained automotive PCBs where full isolation is mandatory.

Frequently Asked Questions

What is the switching frequency of the XSN6505BQDBVTQ1?

The XSN6505BQDBVTQ1 operates at a fixed switching frequency of 420 kHz, which reduces the size of the external transformer and filter components while keeping switching noise outside sensitive audio and signal frequency bands.

What supply voltage range does the XSN6505BQDBVTQ1 support?

The XSN6505BQDBVTQ1 operates from a supply voltage of 2.25 V minimum to 5.5 V maximum, making it compatible with both 3.3 V and 5 V system power rails commonly found in automotive ECUs.

Is the XSN6505BQDBVTQ1 qualified for automotive applications?

Yes, the XSN6505BQDBVTQ1 carries AEC-Q100 screening, qualifying it for automotive applications such as isolated CAN transceivers, LIN nodes, and sensor power supplies where long-term reliability under temperature stress is required.

What package does the XSN6505BQDBVTQ1 use?

The XSN6505BQDBVTQ1 is available in a 6-pin SOT-23 (JESD-30 code R-PDSO-G6) small outline package, offering a very small PCB footprint suitable for tight automotive PCB layouts.
