smcs emc6d103s datasheet is a fan control device with high frequency pwm support and hardware monitoring features
The EMC6D103S is an environmental monitoring and fan‑control IC that supports high‑frequency PWM outputs, hardware monitoring of up to five voltages and three thermal zones, and SMBus 2.0 communication. It is offered in a 24‑pin SSOP, lead‑free, RoHS‑compliant package.
Key features include 3 PWM fan‑speed outputs, 4 fan tachometer inputs, programmable automatic fan control based on temperature zones, two low‑power modes (Sleep and Shutdown), and a range of limit‑comparison registers for voltage and temperature protection.
| Operating Voltage | 3.3 V (5 V tolerant input buffers) |
|---|---|
| SMBus Interface | SMBus 2.0 compliant with three slave address options |
| PWM Outputs | 3 PWM fan‑speed outputs |
| Fan Tachometer Inputs | 4 inputs |
| Voltage Monitoring Channels | Monitors up to 5 voltages |
| Thermal Zones | 3 zones (2 external, 1 internal) |
| Package | 24‑pin SSOP, lead‑free, RoHS compliant |
It supports two monitoring modes: Continuous Mode and Cycle Mode.
The device can monitor three thermal zones – two external zones and one internal zone.
The EMC6D103S can operate in Sleep mode or Shutdown mode for power savings.
The IC provides three PWM fan‑speed outputs and four fan tachometer inputs.
