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
