3-Phase BLDC Motor Driver IC
ECN30204
P1/16
The ECN30204 is a fully integrated BLDC motor driver IC that facilitates a rapid design
process and low part count solution. The IC integrates a commutation-logic, a PWM
signal generator, IGBTs, FWDs(Free Wheeling Diodes), a charge pump, protection
circuits, etc.
The IC can drive a BLDC motor with a high voltage DC power supply (up to 450VDC)
directly rectified from AC power line (up to 230VAC) for downsizing a system and
reducing power consumption.
Description
· Integrated, Single-Chip 3-Phase BLDC Motor Driver IC.
· Integrated Charge Pump – Constant TOP Arm bias independent of motor speed.
· Integrated 3-Phase Brushless (Electronic) commutation via external Hall ICs.
· Integrated 3-Phase 6-IGBT Motor Bridge with on chip Free-Wheeling diodes.
· Pinout and Board Layout are compatible with the existing Hitachi ECN3022.
· Maximum Ratings 500VDC/1.5A.
· Latch-Up free monolithic IC built with a high voltage Dielectrically Isolated (DI) process.
· Available in 3 package types with built-in heat sink (Tab).
Functions and Features
· Vs Operating Voltage Range from 15VDC up to 450VDC.
· Simple Variable Speed Control via a single (VSP) analog input.
· PWM duty cycle generator provides the 0% to 100% speed control range.
· Tachometer – Generates the (RPM/60) (P/2) 3 Hz speed signal (FG).
· BOTTOM Arms switch at up to 20kHz via an on-chip OSC/PWM.
· On-Chip 7.5VDC regulator (CB) with the guaranteed external Min load (25mA).
· Over-Current protection is set by an external Sense Resistor (RS).
· Under-Voltage protection for TOP and BOTTOM IGBT Arms.
· All output IGBT Shut-OFF function.

8.10 Lead(Pb)-free solder is used for coating pins and the tab of this IC. In case of flow soldering*, the IC
can withstand peak temperature 260oC for less than 10 seconds in liquid solder.
*Only pins are in liquid solder. The package body and the tab must not be in it.
9. Important Notices
9.1 Hitachi warrants performance of its power semiconductor products (hereinafter called “products”) to the
specifications applicable at the time of sale in accordance with the Product Specification. Testing and
other quality control techniques are utilized to the extent Hitachi needs to meet specifications described
in the Product Specification. Specific testing of all parameters of each device is not necessarily
performed, except those mandated by related laws and/or regulations.
9.2 Should any claim be made within one month of product delivery about products’ failure to meet
performance described in the Product Specification, all the products in relevant lot(s) shall be retested
and re-delivered. Products delivered more than one month before of such claim shall not be counted for
such response.
9.3 Hitachi assumes no obligation or any way of compensation should any fault about customer’s goods
using products be found in marketplace. Only in such a case fault of Hitachi is evident and products
concerned do not meet the Product Specification, compensation shall be conducted if claimed within
one year of product delivery up to in the way of product replacement or payment of equivalent amount.
9.4 Hitachi reserves the right to make changes in the Product Specification and to discontinue mass
production of the relevant products without notice. Customers are advised before purchasing to confirm
specification of the product of inquiry is the latest version and that the relevant product is on
massproduction status in such a case purchasing is suspended for one year or more.
9.5 In no event shall Hitachi be liable for any damage that may result from an accident or any other cause
during operation of the user’s units according to this Product Specification. Hitachi assumes no
responsibility for any intellectual property claims or any other problems that may result from applications
of information, products or circuits described in this Product Specification.
9.6 No license is granted by this Product Specification under any patents or other rights of any third party or
Hitachi, Ltd.
9.7 This Product Specification may not be reproduced or duplicated, in any form, in whole or in part without
the expressed written permission of Hitachi, Ltd.
