TPIC46L01DBR

The TPIC46L01DBR from Texas Instruments is a 6-channel, low-side pre-FET driver with both serial and parallel input interfaces. It is designed primarily for low-frequency switching applications involving inductive loads such as solenoids and relays. Each driver channel offers independent off-state open-load detection and on-state shorted-load/short-to-battery detection. The device also provides over-battery voltage lockout protection and fault reporting, with under-battery voltage lockout protection available for specific models.

Key electrical specifications include a peak output current of 1.2mA per channel, an input supply voltage range of 4.5V to 5.5V, and CMOS compatible inputs. It supports N-Channel MOSFET gates and operates with non-inverting logic. The device features rise and fall times of 3500ns and 3000ns respectively, with a propagation delay of 5µs.

Packaged in a 28-SSOP (0.209", 5.30mm Width) surface-mount configuration, the TPIC46L01DBR operates within an ambient temperature range of -40°C to 150°C (TJ). Its design includes internal 55-V inductive load clamp and VGS protection for external power FETs, and an asynchronous open-drain fault flag. The device can be cascaded and its output can be wire-ORed with multiple external devices for expanded functionality.
