the TPIC46L01, TPIC46L02, and TPIC46L03 are low-side predrivers that provide serial input interface and parallel input interface to control six external field-effect transistor(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 port (SDA).
The TPIC46L01, TPIC46L02, and TPIC46L03 are low‑side pre‑drivers that provide both serial and parallel input interfaces to control six external FET power switches. Each channel includes independent open‑load and shorted‑load fault detection, battery over‑ and under‑voltage protection, and inductive‑transient protection.
The document lists electrical characteristics, pin functions, absolute maximum ratings, recommended operating conditions, switching parameters, mechanical dimensions, and an important notice about warranty and critical‑application use. It also shows timing diagrams for serial and parallel operation and provides mechanical drawing data for the DB package.
| Supply voltage range (VCC) | -0.3 V to 7 V |
|---|---|
| Logic supply voltage (Voc) | 4.5 V – 5.5 V (typ. 5.0 V) |
| Battery supply voltage (VBAT) | 8 V – 24 V |
| High‑level input voltage (ViH) | 0.85 × Voc |
| Low‑level input voltage (VIL) | 0 – 0.15 × Voc |
If a shorted‑load fault occurs, the channel is turned off and a fault signal is sent to the FLT pin and the serial fault register.
The typical logic supply voltage is 5.0 V, with a minimum of 4.5 V and a maximum of 5.5 V.
Yes, the devices are designed to allow the serial input interfaces of multiple devices to be cascaded together, each requiring 8 bits of data per device.
