Relay driver ic uln2003 pin diagram.

High side relay driver ic.

Included are the following. What are the pros and cons of low side versus high side relay driving concepts in an automotive environment. Ic pwr driver npn 1 1 16soic. 8 channel high side driver vs spider.

µc qfn32l5 e520 02 soic28 e520 02 qfn20l5 e520 08 soic20 e520 08. 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. 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.

The questions popped up when i was looking for an 8 channel relay driver ic for a automotive ecu project. Passive tunable integrated circuits ptics 9 ptic controllers 3 wireless rf transceivers. Ic pwr driver n chan 1 1 16tssop. 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.

High side driven low side driven bi stabil. Relay driver ic uln2003. 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.

Monolithic microwave integrated circuits mmic tunable components. The ic uln2003a is a darlington transistor array which deals with high voltage and high current. 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.

You may recall the tlc555 relay driver circuit that i recently posted it too is a low side driver. Charge pumps 8 controllers 113. 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. High side switches can safely drive high currents into complex resistive inductive and capacitive grounded loads in compliance with the harsh automotive environment.

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.
