St offers a series of intelligent power switches ips for high side and low side configurations.
High side switch chip.
The high side switches have on resistance of 250mω max at 125 c ambient temperature.
1000 pf in 60 µs.
With over current shutdown and a fault flag.
The switch is controlled by a logic enable compatible with 5 v logic and 3 v logic.
The max14912 max14913 have eight 640ma smart high side switches that can also be configured as push pull drivers for high speed switching.
These devices integrate the control section logic interface drivers diagnostic and protection features and the power stage on the same chip with benefits in terms of compactness increased system reliability and cost effectiveness.
This requires both a robust low on resistance power switch and accurate analog circuitry for diagnostic protection and control functions.
A useful circuit to have in designer s toolbox is the high side switch.
Typically these use a pnp bjt or p channel mosfet.
The spi interface has a built in chip addressing decoder allowing communication with multiple max14915s utilizing a common spi chip select active low cs.
The propagation delay from input to switching of the high side low side drivers is 1µs max.
1000 pf in 60µs.
The opposite of the low side switch is the high side switch.
High side or low side single.
Gate drive is provided by an internal charge pump designed to control the power switch rise times and fall times to minimize current surges during switching.
These devices are 50 m n channel mosfet high side power switches.
The high side drivers come with high side referenced output channels to control power devices like mosfets and igbts.
Like it sounds this is a circuit that switches the high side or positive voltage to a load.
They are perfect for applications like aircon automotive solar.
High side drivers could be automotive gate drivers gan eicedriver gate driver ics galvanic isolated gate driver 500 700v level shift gate driver eicedriver 1ed compact and µhvic gate driver ics.
The max14915 has eight high side switches specified to deliver up to 700ma continuous current.
Less than 1µa in standby mode.
High side switches can safely drive high currents into complex resistive inductive and capacitive grounded loads in compliance with the harsh automotive environment.
This transistor connects between v and the load.
A larger chip.
