High Side Driver With Current Sense

High side drivers respectively which have a high output drive 1a source 2a sink.

High side driver with current sense.

The max16834 s integrated high side current sense amplifier eliminates the need for a separate high side led current sense amplifier in boost buck applications. Neubean goes to the lab and dials up a sense current with the high side sense circuit ltc2063. The current sensing circuit for these two devices uses a timing circuit via the err pin to program the time between over current detection and latched shutdown. Output current limitation protects the device in overload condition.

This device integrates an analog current sense which delivers a current proportional to the load current according to a known ratio when cs dis is driven low or left open. The max16834 operates over a wide supply range of 4 75v to 28v and includes a 3a sink source gate driver for driving a power mosfet in high power led driver applications. He inserts a high r gate value first 100 kω and then 1 mω expecting to see unstable behavior or at least some kind of ringing. The ir2127 and ir2128 are both high side drivers ir2127 active high input ir2128.

Simple to optimize for efficiency board space and input operating range. The selection depends purely on the application that detect the sense current. Boost sepic and buck boost single channel led drivers. The terms high side and low side refer to the insertion of the sensing element whether inserted between positive supply and the load or between the load and the negative supply ground.

When cs dis is driven high the current sense pin is in a high impedance condition. 2 accurate 1 64v reference max16833b d programmable operating frequency 100khz to1mhz with synchronization capability.
