FAN3121 Datasheet (fan3121 / Fan3122) Low-side Gate Driver

Manufacturer: Fairchild (now onsemi)

Overview: FAN3121 / FAN3122 — Single 9A High-Speed, Low-Side Gate Driver ..

General Description

The FAN3121 and FAN3122 MOSFET drivers are designed to drive N-channel enhancement MOSFETs in low-side switching applications by providing high peak current pulses.

The drivers are available with either TTL (FAN312xT) or CMOS (FAN312xC) input thresholds.

Internal circuitry provides an under-voltage lockout function by holding the output low until the supply voltage is within the operating range.

Key Features
