The device is the industry's first -48 V wide input voltage digital hot-swap controller with a programmable safe operating area (SOA) control designed for telecom infrastructure.
It provides superior current reporting accuracy of less than ±0.7 percent, enhancing the system's fault detection and reporting accuracy. Furthermore, the product features boost-mode control technology for safer turn-on of field-effect transistors (FETs) in systems with non-optimal SOA.
This new member of the XDP product family is tailored for a spectrum of telecom applications, including remote radio head power, base station power distribution, active and passive antenna systems, 5G small cell power, and telecom UPS systems.
The XDP700-002 employs a three-block architecture that combines high-precision telemetry for monitoring and fault detection, digital SOA control optimised for power MOSFETs, and integrated gate drivers for n-channel power MOSFETs.
The XDP700-002 operates within an expansive -6.5 to -80 V input voltage range and can withstand transients up to -100 V for 500 ms, delivering current and voltage telemetry with a remarkable 0.7 percent and 0.5 percent accuracy respectively. It features precise PMBus compliant active monitoring for enhanced system reliability. A programmable gate shutdown during severe overcurrent (SOC) ensures robust shutdown operation within just 1 µs. The advanced closed-loop SOA control ensures higher MOSFET reliability, and the fully digital operating mode minimises the need for external components offering a compact solution making it an optimal fit for space-constrained designs in a cost-effective way.
With options for external FETs selection and a one-time programmable (OTP) option, the XDP700-002 offers flexibility for programming faults and warnings detection as well as de-glitch levels for various usage models.
Its analogue-assisted digital mode offers backward compatibility with legacy analogue hotswap controllers. By offering robust functionality and adaptability, the XDP700-002 exemplifies Infineon's continuous commitment to innovation and system reliability in telecom infrastructure.
The controller matches Infineon's OptiMOS and OptiMOS Linear FET portfolio for reliable and powerful system performance.
The XDP700-002 hot-swap and system monitoring controller IC is available in a VQFN-29 6x6 package and can be ordered now.
