Part Number: LM1949 My customer is evaluating using LM1949 (-55ºC)
The data from the control of the brake of an electric motor are:
Winding resistance: 3.2 Ohm 10% Inductance: 1.6 Henry +/- 30% Release current: I> 3.2 A kept during at least 150 msec…
Part Number: LM1949 Other Parts Discussed in Thread: DRV120 Is it possible to get a SPICE model of the LM1949 for aid in debugging ? I am having difficulties with an application using the LM1949 solenoid valve controller. It is cycling the driver transistor…
Part Number: LM1949 Hi Experts,
Good day.
Will this device work without any degrade at 6.0V supply voltage? D/S shows it normally powered up to 5.5V only.
Thank you.

Part Number: LM1949 Hi,
We are designing a diesel ECU. Want to know the suitability of using LM1949 device for driving the diesel injectors. The diesel injectors require 75V DC.
Whether LM1949 along with 2N6044 be used to drive Diesel injectors? …
Part Number: LM1949 Hi team,
My customer is using LM1949 as solenoid driver in a valve project. According to the datasheet, the minimum input frequency is 10Hz. They would like to know whether it is feasible to use it at 5Hz and what will be the risk…
Part Number: LM1949 Hi,
I am designing a fuel injection circuit that requires limiting the injector current. The injector resistance is ~1-Ohm. The LM1949 does exactly what I am looking for, BUT I have the following concerns/questions:
(1) The device…
Part Number: LM1949 Other Parts Discussed in Thread: DRV110 I have a requirement for a specific injector that wants the peak current drive to be held at 3A for 2 mS followed by the drop to the hold current level of 0.75A.
From what I can tell from reading…
Hi Haris,
I'm glad you think the LM1949 will work for your application. Generally, when asked for a solenoid driver similar to DRV110 (relay/contactor driver), I suggest some of the following in this voltage range:
DRV8803
DRV8860
DRV8952
Please…
Hey Dan,
LM120K-5.0/883 is indeed obsolete. I've attached the PDN.
We don't have an exact P2P replacement so I'd recommend the UA79 series as the closest alternatives.
