KTA1170GVAE-TB

Overview

The KTA1170GVAE-TB is a Power Over Ethernet (PoE) Powered Device IC compliant with IEEE Std. 802.3bt. It integrates dual MOSFET bridge rectifiers and TVS protection within an 8-WDFN package. Key electrical parameters include a maximum on-resistance of 300 mOhms, a current limit of 600 mA, and operation at 48 V. The device supports up to 90 W output power across two channels, with a supply voltage range of 2.7V to 75V and operating temperatures from -40°C to +125°C.

Feature Summary

Integrates dual MOSFET bridge rectifiers for efficient PoE power conversion
Includes built-in transient voltage suppression (TVS) for circuit protection
Supports high-power applications up to 90 W under IEEE 802.3bt standards

Applications

IEEE 802.3bt PoE powered devices
LAN integrated power management systems
Dual-channel bridge rectification circuits

Procurement Notes

Verify the specific suffix TB against official Kinetic Technologies documentation to confirm exact packaging and reel specifications. Ensure compatibility with IEEE 802.3bt requirements for your design. Cross-reference the 8-WDFN footprint dimensions during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when designing PoE endpoints requiring integrated rectification and protection in a compact form factor. The dual-channel architecture suits applications needing independent or combined power paths. Consider the 300 mOhm on-resistance for thermal management calculations. Verify that the 600 mA current limit aligns with the load requirements of the target system.
