The AAM119A is the first in a developing family of Brushed DC Motor Controller products. This offering was designed as a
feature-rich controller, providing a wide range of support features to enable a variety of in-circuit configurations. Used while driving an external Power MOSFET or IGBT, it is possible to create a closed loop system with either a Linear or PWM-based control scheme for a variety of loads.
An on-board operational amplifier provides for scaling of monitored signals for purposes of closed loop feedback. The externally set control can be implemented with either duty cycle control of a 25Hz to 10kHz PWM signal averaged through an external capacitor, or an input DC level of 0V to 5V. A programmable Stand-By threshold for the input DC(in) level is set via the OTP function, referenced either to the internal 5V reference or ground as set by the selected polarity of the PWM signal. The 5V On-Board Linear Regulator will operate even in Stand-By, drawing only 300µA.
