SLG55021-200010V GreenFETTM High Voltage Gate Driver
●Overview
■The SLG55021 N-Channel FET Gate Driver is used for controlling a delayed turn on and ramping slew rate of the source voltage on N-Channel FET switches from a CMOS logic level input. Intended as a supporting control element for switched voltage rails in energy efficient, advanced power management systems, the SLG55021 also integrates circuits to discharge opened switched voltage rails. The gate driver is available in a variety of configurations supporting a range of turn-on slew rates from 0.80V/ms up to 4V/ms which, depending on load supplying source voltages in the range of 1.0V to 20V results in ramp times from 200μs up to over 20ms. Delays until the ramp begins are source voltage independent and range from 250μs to 5ms. A power good condition is output to indicate that the ramp-up slew of the source voltage is finished. Additionally, an internal discharge circuit provides a controlled path to remove charge from open power rails. The SLG55021 gate drive is packaged in an 8 pin DFN package.
■When used with external N-Channel FETs, the SLG55021 supports low transient, energy efficient switching of high current loads at source voltages ranging from 1.0V to 20V.
