该TPIC44L01，TPIC44L02和TPIC44L03是低端预驱动器提供串行和并行输入接口，四个外部FET的电源控制，例如在TI TPIC阵列系列提供的电源开关。 These devices are mainly used in applications with inductive loads such as low frequency switches, solenoid valves, and relays. Each channel fault status provides a serial data format. Each drive channel has independent off-state, open-load detection, and shorted-load/short-to-battery detection. 电池过压，欠压检测和关闭是提供了TPIC44L01/L02。 在TPIC44L03驱动程序，只过压关断电池提供。 每个通道还提供了电感式电压瞬态外部FET的保护。
