ST’s L98GD8 multichannel gate driver affords versatile output configurations in 48-V automotive energy methods. Its eight unbiased, configurable outputs can drive MOSFETs as particular person energy switches or as high- and low-side pairs in as much as two H-bridges for DC motor management. The system additionally helps peak-and-hold operation for electrically actuated valves.
Programmable gate present helps decrease MOSFET switching noise to fulfill EMC necessities. The motive force operates from a 3.8-V to 58-V battery provide and a 4.5-V to five.5-V VDD provide. Its I/O is suitable with each 3.3-V and 5-V logic ranges.
To make sure security and reliability, every output gives complete diagnostics, together with short-to-battery, short-to-ground, and open-load circumstances. Output standing is repeatedly monitored via devoted SPI registers. The L98GD8 options quick overcurrent shutdown with dual-redundant failsafe pins, battery undervoltage detection, and an ADC for monitoring battery voltage and die temperature. Extra security features embrace Constructed-In Self-Take a look at (BIST), {Hardware} Self-Verify (HWSC), and a Communication Verify (CC) watchdog timer.
The L98GD8 driver is offered now, with costs beginning at $3.94 every in plenty of 1000 items.
