FAN3121CMX屬于集成電路（IC）的柵極驅(qū)動(dòng)器。由安森美半導(dǎo)體公司制造生產(chǎn)的FAN3121CMX柵極驅(qū)動(dòng)器柵極驅(qū)動(dòng)器電源管理集成電路 (PMIC) 可用于提供隔離、放大、參考位移、自舉或其他必要功能，這些功能可將來(lái)自電源轉(zhuǎn)換應(yīng)用中控制設(shè)備的信號(hào)連接到電源被控制通過(guò)的半導(dǎo)體設(shè)備（通常為 FET 或 IGBT）。任何特定設(shè)備提供的確切功能各不相同，但與它適合驅(qū)動(dòng)的半導(dǎo)體配置相關(guān)。

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 input thresholds (FAN312xT) or

VDD?proportional CMOS input thresholds (FAN312xC). Internal

circuitry provides an under?voltage lockout function by holding the

output low until the supply voltage is within the operating range.

FAN312x drivers incorporate the MillerDrive architecture for the

final output stage. This bipolar / MOSFET combination provides the

highest peak current during the Miller plateau stage of the MOSFET

turn?on / turn?off process.

The FAN3121 and FAN3122 drivers implement an enable function

on pin 3 (EN), previously unused in the industry?standard pin?out.

The pin is internally pulled up to VDD for active HIGH logic and can

be left open for standard operation.

The commercial FAN3121/22 is available in a 3x3 mm 8?lead

thermally?enhanced MLP package or an 8?lead SOIC package. The

AEC?Q100 automotive?qualified versions are available in the 8?lead

SOIC package.
