Part Number: MSP430G2553 Other Parts Discussed in Thread: DRV8702-Q1 , , DRV8702-Q1EVM , MSP-FET Tool/software: Code Composer Studio Greetings,
I have no experience in CCs and for this reason I would really appreciate if you can answer in the easiest…
Hi Bogey,
Assuming 3.7A RMS, the DRV8873 may not be the optimal choice. At 3.7A RMS, the device power may exceed 4W.
The DRV8412 in parallel mode can support up to 6A continuous. Figure 17 of the datasheet shows the connections.
We have gate driver…
Hi Vitali,
The current values listed in Table 2 are per bridge. A 24k OC_ADJ resistor is ~21.4A peak current. This varies due to any mismatch in the two bridges.
If you need more current, please consider a gate driver like the DRV8701, DRV8702-Q1…
Hi liur,
It is not recommended to connect the two in parallel. There can be a difference in propagation delay as you mentioned.
Please consider one of the devices here: www.ti.com/.../products.html
If you require more current, the DRV8702-Q1…
Hello Simon,
Our DCDC portfolio is separate from our motor driver portfolio. I support motor drivers, so I may be able to help.
If you are driving currents larger than 10 A, you may be interested in one of the devices from our gate driver portfolio…
Hi Milordy,
The majority of high current brushed drivers use N-channel FETs for both the high and low side. This is done by integrating either a charge pump or a bootstrap capacitor.
If you desire 100% operation, the charge pump is the preferred choice…
Hi Nagasawa-san,
There should be plenty of margin. Typically the FETs switch in a few microseconds.
It is important to use the proper IDRIVE setting to achieve proper switching speeds.
(3) Is it possible only enable VSP(OCP) by pull up VDS pin…
Brian,
The DRV8701, DRV8702-Q1, DRV8702D-Q1, DRV8703-Q1, and DRV8703D-Q1 are our closest devices. Speed control and hall-sensor feedback may need to be controlled by external circuitry. We do not integrate those features in these devices.
TIDA-00875…
Hi na na78,
We have several devices that may work.
The DRV8701, DRV8702-Q1, and DRV8703-Q1 are H bridge gate drivers. The DRV8704 is a dual H bridge gate driver.
Also many of our BLDC gate drivers such as the DRV8320, DRV8323, and DRV8301 can be…
