Part Number: BQ2018 Hello, we are using the BQ2108 power meter to communicate with the device. The battery pack we are using for the first time does not display the actual power when installed on the device. The actual voltage is around 10.6V, and the…
Part Number: BQ2018 Other Parts Discussed in Thread: BQSTUDIO , BQEVSW , EV2400 We are still using the bq2018 for an old project. Here we have problems with communication and therefore need a tool to be able to communicate with the bq2018 on our board…
Part Number: BQ2018 Tool/software: I am requesting the models because I need them for a signal integrity analysis in Altium. The project consists of a PCB for a Battery Management System. This analysis will help us decide which of the two designs we have…
Part Number: BQ2018 Hi Sir,
As I know, we have G4 version is lead-free device.
My customer would like order BQ2018TS-E1TRG4, but there is no such MPN as “BQ2018TS-E1TRG4” in SAP now.
Could you please check and advise again if “BQ2018TS-E1TR” do…
Other Parts Discussed in Thread: BQ2018 , MSP430F2618 , BQ27010 Hi,
I'm using an MSP430F2618 ucontroller to transmit and receive messages with the BQ2018 Power Minder IC. I am able to transmit and receive if I have a pull-up resistor on the HDQ line…
Part Number: BQ34Z110 Other Parts Discussed in Thread: BQ2018 , , BQ76942 , BQ34Z100-G1 HI. I am wanting to monitor state of charge for individual lead-acid batteries in a battery bank of 55. Each battery is 2V and could be 100amp or 200amp. i saw datasheet…
Hi,
We do not recommend programming the gauge in hdq because of the speed, but rather in i2c mode. While in the field communication is via hdq. I do not have sample code, but you can read registers from the gauge using bqstudio and sniff the bus. Also…
Hi Andy,
HDQ comm protocol doesn't have an ACK like Smbus or I2C. That is a limitation of the protocol. pls see attached app notes to offer guidiance on using the hdq protocol.

In the EVSW, the settings for the comm port are 9600 Baud, no parity, 8 bits, 1 stop bit. I've attached the communication document for the EV2200. You will find the HDQ commands in there.
