TPIC44L02 4 通道串联/并联高端前置 FET 驱动器
The TPIC44L01, TPIC44L02, and TPIC44L03 are low-side predrivers that provide serial and parallel input interfaces to control four external FET power switches such as offered in the TI TPIC family of power arrays. These devices are designed primarily for low-frequency switching, inductive load applications such as solenoids and relays. Fault status for each channel is available in a serial-data format. Each driver channel has independent off-state open-load detection and on-state shorted-load/short-to-battery detection. Battery overvoltage and undervoltage detection and shutdown is provided on the TPIC44L01/L02. On the TPIC44L03 driver, only over-battery voltage shutdown is provided. Each channel also provides inductive-voltage-transient protection for the external FET.
