Design considerations
- Controlling coil current is the key to injector fuel accuracy, with ‘pull-in’ requiring large currents while less current is needed to ‘hold’
- N-channel MOSFETs for switch pull-in, hold current and cylinder select need high current transient robustness
- Schottky rectifier or PN rectifier for freewheeling and protection of inductive load
- Ensure adequate suppression and filtering of EMI noise
- Using 100 V, ultra-low-leakage Schottky technology helps prevent thermal runaway
Driving efficiency takes pole position
Today’s cars are undergoing the greatest transformation the industry has seen. Continued electrification is resulting in significant change from the engine right through to the cloud. Consistently delivering the right functionality, with the right performance, in the right package is how Nexperia is helping ‘driving efficiency’ win.
Automotive relay replacement - Reliability meets space savings
A relay is often perceived as the ideal device with perfect input/output isolation. Unfortunately, this is not the case. MOSFETs are rapidly becoming the option of choice offer reliability and space savings.
