Part Number: LM57-Q1 Other Parts Discussed in Thread: LM57
Dear support team:
Our customer requests 15 degree in hysteresis.
As one method, they change Trip point dynamically.
Their requirment is 85 degree and 70 degree.(hysteresis is 15 degree)
At first…
Other Parts Discussed in Thread: LM57 I am working with a circuit that has an LM57C. The trip point seems to be about 15 degrees C higher than it should be. I expect it to trip at 59.3 degrees, but it doesn't trip until it reaches around 75 degrees.…
Other Parts Discussed in Thread: LM57 Hi,
Is there any data on how long it takes the sensor to respond to a change in temperature? I know on the LM57 datasheet on page 9 and 11, there is "start up response time" data, but that data seems to correspond…
Other Parts Discussed in Thread: LM57 , LM26 , LM26LV I am using an LM57 device to initiate an automatic thermal override shutdown of an induction heater. Here is the LM57 portion of schematic.
R3: 280K, ±1% ±100ppm/°C digikey part number…
Other Parts Discussed in Thread: LM57 , LM26LV , LM35 Dear,
in the datasheets for LM26LV, LM57 there is stated that "best thermal conductivity between the device and the PCB is achieved by soldering the DAP of the package to the thermal pad on the PCB. …
Other Parts Discussed in Thread: LM57 I have an application using a LM57 temperature sensor set to trip at -34.5C.
During in-circuit testing the value of Rsense2 is connected to 0V to force TOVER in-active at room temperature.
From the datasheet it appears…
Other Parts Discussed in Thread: LM57 , MSP430F5310 Hi Everyone
I have a strange issue with using the TI MSP430F5310 ADC and the TI LM57 temp sensor. the Rsense values are at 46.4k and 499.9k for Rsense1/Rsense2.
The issue is that, when my device(board…
Other Parts Discussed in Thread: LM57 I would like to design a simple board which controls a resistor as a heater. At T(1), heater (resistor) will be ON and at T(2), heater will be OFF and T(1)<T(2). I can set the R(SENSE) and hysteresis values and if…
Other Parts Discussed in Thread: LM57 Hi,
1. Do I need to connect the Thermal Pad to GND? The pad is connected to GND and I see (-6) Celsius when the device is in room temp, is it related to the Pad?
2. When checking Pin8 with DVM(in Trip Test mode) I…
