Part Number: TPL7407LA Other Parts Discussed in Thread: ULN2003A , TPL7407L , The applications for low-side switching are far reaching, with loads ranging from relays to solenoids, LEDs to lamps, etc.
The ULN2003A for example is so widely used, it has its…
Part Number: TPL7407L Hi team,
As shown in the datasheet, if the application has an inductive load connected to OUT7, it is recommended to use an external Schottky diode to protect the OUT7 pin from negative transients larger than those listed…
Part Number: TPL7407L Hi team,
My customer use TPL7407L in their project, and they met below issue, could you please help give some comments or suggestions?
Thank you!
The customer connect 5V or 12V relay in the output pin, and occasionally the output…
Hello Daniel,
It is unsurprising if the inrush current is causing the damage since each channel is rated to 600mA. If your PWM control is independent of your power on control you can use a by-pass capacitor on the PWM power node to provide the inrush…
Part Number: TPL7407L Hello, Mr. / MS
I expect to use the TPL7407L to design the digital output circuit of PLC. What I ask is how to design the peripheral circuit of this chip, so that it has the ability of short circuit protection.Is there a reference…

Tpl7407l is used for the seat ventilation heating project . At present, the part damage rate is too high. Customers found the problem is caused by the low level of static…
Part Number: TPL7407L The DS states the minimum recommended COM voltage is 8.5V, but that lower voltages will work at the expense of higher RDSON.
Can you provide any information regarding RDSON when COM = 5V?
