MC17XS6500CEKR2

Overview

The MC17XS6500CEKR2 is a six-channel smart high-side power distribution switch manufactured by NXP Semiconductors. It features an N-channel output configuration with a typical on-resistance of 17 milliohms per channel. The device operates within a load voltage range of 7V to 18V and requires a supply voltage between 4.5V and 5.5V. Communication is handled via a Serial Peripheral Interface (SPI). Integrated protection mechanisms include fixed current limiting, open-load detection, and over-temperature shutdown. The component is housed in a 32-pin HSOP package with exposed pad for thermal management.

Feature Summary

• Six independent high-side switching channels with low on-resistance
