Hi Samuel,
We recommend taking a look at the transient thermal resistance and current capability table in section 5.4.1 of the datasheet. Based on the information in the table, this device is going to best handle a 7A load for extended periods with…
Other Parts Discussed in Thread: DRV8144-Q1 , DRV8145-Q1 Hi everyone,
I need help about a design to control a selenoid (half-bridge) but the critical point is the junction temperature; -40 to 170ºc.I was looking at DRV8144-Q1 but it works until 125…
Other Parts Discussed in Thread: DRV8143-Q1 , DRV8145-Q1 , DRV8144-Q1 DRV8143-Q1, DRV8144-Q1, DRV8145-Q1 has H-Variant.
In H-Variant(HW interface), nSLEEP pin requires external pulse input. It should be 20us-40us pulse to wake the parts.
20us-40us…
Part Number: DRV8912-Q1 Other Parts Discussed in Thread: DRV8143-Q1 , DRV8144-Q1 Hi,
Can we parallel the outputs between two DRV8912 to (1) have a overall higher driving current (ex. 7A), or (2) reduce the temp rise for each part when driving say 6A…
Part Number: DRV8145-Q1 Other Parts Discussed in Thread: DRV8144-Q1 Hello,
Can I use the DRV8145 for the purpose of driving this foil rated at 12V 100W ?
The driving frequency should be around just 200Hz.
Thanks in advance.
Best,

Hi,
Our application requires to run motor at 10A for 0.5 ms. We ran into a problem where the total output current from a custom board with DRV8243HQRXYRQ1…
Other Parts Discussed in Thread: DRV8144-Q1 , DRV8143-Q1 , DRV8145-Q1 Hi Team,
Could you help recommend a motor which is able to meet the following requirements:
a. Voltage is greater than 16V.
b. Current ≥ 20A.
c. PWM control.
d. With current…
HI,
It is difficult to simulate exactly your load condition, But I tried here. I focused on 180ms sine wave period. I think this is most critical period for thermal. I generated 3 sinewave with 15.9A peak instead of ~10pulses on your measurement.

Hello Bing,
Bing Li said: 1. Does the output pin of DRV8244 connect together to increase the current capability? I just need a half bridge with bigger load current.
While this can be done I would recommend taking a look at the DRV8144 for a better…
