Power+ FET pre-driversTI's latest Power+ª chipsets offer separate FET pre-drivers and power DMOS arrays. This new chipset approach offers designers the flexibility to tailor the output stage FETs and on-resistances to meet a specific load requirement. They provide a cost-effective alternative to traditional single-chip custom solutions, often characterized by high risk and long development time.
 This new family offers a 6-channel (TPIC46L01/02) and 4-channel (TPIC44L01/02) solution for switching inductive loads such as solenoids, valves, relays, lamps and motors. The family is well-suited for applications such as engine control systems, automotive safety systems, control systems, robotics and electronic data processing. The TPIC46L01/02 and TPIC44L01/02 (02 version offers an auto enable) are low-side FET pre-drivers designed primarily for low frequency switching. These devices are cascadable and offer diagnostics with real-time fault status returned through the serial output. The pre-drivers outputs feature inductive voltage transient protection and high impedance inputs with hysteresis. The TPIC2601 and TPIC2401 are monolithic power arrays that consist of electrically isolated N-channel, enhancement-mode, DMOS transistors configured with common source and open drains. The devices feature integrated high-current diodes to provide 2000 V ESD protection (human body model) and gate damage overstress protection. Separating the power section from the control offers an added benefit by allowing a standard pre-driver to interface to various power switches. Features
