High Side Relay Driver Ic

Relay driver ic uln2003 pin diagram.

High side relay driver ic.

The relay driver uln2003 ic is a high voltage and current darlington array ic it comprises of 7 open collector darlington pairs with common emitters. Infineon s smart high side switches includes more than 200 products in 12 different packages and with a rdson varying from 1mω to 1000 mω. Monolithic microwave integrated circuits mmic tunable components. The questions popped up when i was looking for an 8 channel relay driver ic for a automotive ecu project.

Ac dc led drivers 50 dc dc led drivers 37 linear led drivers 51 dc dc controllers converters regulators. This requires both a robust low on resistance power switch and accurate analog circuitry for diagnostic protection and control functions. µc qfn32l5 e520 02 soic28 e520 02 qfn20l5 e520 08 soic20 e520 08. A pair of darlington is an arrangement of two bipolar transistors.

The new spider family tle75x offers an improved performance higher flexibility up to 6 configurable channels and new channel partitionings e g. 16 soic 0 154 3 90mm width tpl7407lpwr. The spider family tle72x consists of 4 and 8 channel low side and 8 channel low side high side drivers with 2 configurable channels. Charge pumps 8 controllers 113.

There are various types of relay driver ics such as a high side toggle switch low side toggle switch bipolar npn transistor darlington transistor n channel mosfet uln2003 driver ic. Ic pwr driver npn 1 1 16soic. High side toggle switch driver low side toggle switch driver bipolar npn transistor driver darlington transistor driver n channel mosfet driver and uln2003 driver. You may recall the tlc555 relay driver circuit that i recently posted it too is a low side driver.

The target of the video is to show with help of the datasheet and standard electric equations how the pcb is a key contributor to the current capability of our components. E520 02 e520 08 driver ic 12 8x low side relay driver with constant holding current spi 12 08 external. High side driven low side driven bi stabil. It seems like there are more low side driver ic s available but what s actually the pros and cons from the ecu designer point of view.
