Product Brief

BTL Drive Single-phase Full-wave Fan Motor Driver

AM4951/R/2

Description

Parametric Table

(V_CC=12V, T_A=25^oC, unless otherwise noted.)

The AM4951/R/2 series is a single-phase BTL

output fan motor driver designed by bipolar

process. This IC features high efficiency, silent

operation and includes lock shutdown and

automatic restart functions. When the motor is

under lock condition, the lock shutdown function

turns off the output current. When the

lock condition is removed, the IC will

restart automatically and allow DC fan to run. It is

applied for high reliability and low noise

application, such as personal computers, notebook,

car audio, CPU cooling systems and power

supplies in consumer electronics systems.

The AM4951/R series is available in MSOP-8

(12V application only) or PSOP-8 (24V

application only) package. The AM4952 is

available in MSOP-10 package.
