Description

SG6102D is an IC chip manufactured by System General Corp, which falls under the category of electronic components. This chip is specifically designed for a desktop PC's switching mode power supply, which has all the functions required to control and monitor the power supply output. It comes equipped with power good circuitry, remote ON/OFF control, and several protection features against over-power and over-voltage. Additionally, it can directly sense the output rails of over-voltage protection without external dividers.

Specifications and features

Some of the features included with the SG6102D IC chip are:

• PC half-bridge (or 494) power supply supervisor + two 431 + PWM
• High integration & few external components
• Over-voltage protection for 3.3V, 5V, and 12V
• Under-voltage protection for 3.3V, 5V, and 12V
• Under-voltage protection for –12V and/or –5V
• Over-power and short-circuit protection
• Power-down warning circuitry
• Power good circuitry
• Delay time for PSON and PG signal
• Remote ON/OFF function
• On-chip oscillator and error amplifier
• Two shunt regulator for 3.3V and 5V-Standby
• Latching PWM for cycle-by-cycle switching
• Push-pull PWM operation and totem pole outputs
• Soft-start and maximum 93% duty cycle

Application Scenarios

The SG6102D IC chip is perfect for switch-mode power supplies designed for computers like ATX, NLX, and SFX (micro-ATX).

Comparison

• Remote ON/OFF control feature
• Over-voltage protection for multiple voltage levels
• Integrated power-down warning circuitry and power good circuitry

• May not be ideal for applications beyond computer power supply units
