Figure 1. The characteristics of the control voltage and motor current (Torque).
The relationship between the EC-ECR (the
difference between EC (<control voltage> and
ECR <reference voltage>) and the torque is
shown in Figure 1.
The current gain is 0.6A/V (at sensing resistor:
0.5ohm) in both torque directions, and the
dead zone is from
±
0mV to
±
40mV.
When the all short brake mode is selected, the
coil current under the reverse torque control
depends on the back emf. and the coil
resistance.

This IC’s package is POWER-SSOP, so
improving the board on which the IC is
mounted enables a large power dissipation
without a heat sink.
For example, using an 1 layer glass epoxy
resin board, the IC’s power dissipation is 2.9W
at least. And it comes to 4.1W by using an
improved 2 layer board.
The information of the H, I, J type board is
shown in the board information.
