Based on its CurrentPAK technology, the SLG6M6201V is Silego’s first fixed-configuration version of its NVM-programmable CurrentPAK Configurable Mixed-signal IC, or CMIC.

The preceding SLG6M6001V offered full programmability of multiple IC parameters using built-in NVM (Non-Volatile Memory). SLG6M6201V simplifies high-power, 3V power distribution in server and RAID systems by, firstly, setting the output voltage slew rate at 1.6 V/msec to control power-rail in-rush current profile, as well as minimising downstream RFI, while also setting the internal VOUT discharge feature to 300Ω to speed up the discharging of distributed, output capacitive loads, and finally by providing VOUT power-good output signalling to indicate to downstream DC/DC converters and system controllers that the power rail has reached 90% of final value.

The SLG6M6201V offers the system designer the ability of setting the power switch’s dual-level active current limit at 1.25A or 12.5A through an external pin for improved over-current detection in low- or high-load current applications. In an 18-pin 2.0 x 3.0 mm STQFN package, the SLG6M6201V is fully specified from -10°C to 70°C.

Specifications include:

  1. Low RDSON: 3.8 mΩ;
  2. Continuous load current: up to 10A;
  3. Supply voltage range: 3V to 3.6V;
  4. User-selectable, two-level current limit: 12.5A and 1.25A;
  5. Controlled in-rush current: fixed 1.6 V/ms VOUT ramp rate;
  6. Accurate output current sense: 100 µA/A;
  7. Over-temperature protection;
  8. VOUT power good signalling;
  9. Fast internal discharge.
