33926是一款单片集成式H桥电源IC，主要针对汽车电子油门控制而设计，但也能用于电流和电压规格范围内的任何低压DC伺服电机控制应用。\n\n >33926也能控制电感负载，峰值电流可达5.0 A。RMS电流能力取决于器件封装的散热能力。在负载电流达到6.5 A ± 1.5 A以上时，内部峰值电流限制(调节)被激活。当频率达到20 kHz时，可对输出负载进行脉宽调制(PWM)。负载电流反馈功能提供成比例的(0.24%的负载电流)电流输出，可由微控制器的A/D输入来监控。状态标志输出报告欠压、过流和过热故障情况。\n\n 两个独立输入可对两个半桥推挽式输出进行极性控制。两个独立的禁用输入 • 连续工作电压为8.0 V至28 V (瞬态电压范围为5.0 V至40 V)\n • 225 mOhm最大导通电阻 @ 150°C (每个H桥MOSFET)\n • 3.0 V和5.0 V TTL / CMOS逻辑兼容输入\n • 通过内部恒定关断时间PWM进行过流限制(调节)\n • 输出短路保护(VPWR短路或接地短路)\n • 与温度有关的电流限制阈值下降\n • 所有输入均有一个内部源/汇点来定义默认(浮动输入)状态，睡眠模式电流消耗产品长期供货计划中，自推出后至少保证15年供货;
