HIGH-VOLTAGE MONOLITHIC IC
ECN3053F
P1/5
ECN3053 is a single chip driver IC which has 6 MOS-Gated devices for its output.
It is suitable for controlling 3-phase DC brushless motors and 3-phase induction motors.
Functions
Lower arm Over current (OC) Protection
Under voltage Protection
Fault Output function
Package
Features
It can be controlled by PWM with 6 inputs
from an external microprocessor.
6 logic inputs are compatible with 5V CMOS
and LSTTL outputs.

Note 1. Over-current detection level is determined by the following equation
Ioc=Voc/Rs
Note.2 This IC has filters of 0.4us for noise reduction.
But appropriate R1, C1 should be added when noise can not be removed.
