Texas Instruments TPS1211-Q1 High-Side Drivers

Texas Instruments TPS1211-Q1 High-Side Drivers are 45V drivers with protection and diagnostics. These drivers operate at a 3.5V to 40V wide voltage range and are suitable for 12V system designs. The TPS1211-Q1 drivers offer an accurate, current sensing (±2% @30mV) output (IMON), enabling system designs for energy management. These devices integrate a precharge driver (G) with control input (INP_G). Features include output reverse polarity protection down to -30V, 3.7A strong pullup and 4A pulldown gate driver, and drives external back-to-back N-channel MOSFETs. The TPS1211-Q1 drivers are available in a 19-pin VSSOP package with a pin removed between adjacent high-voltage and low-voltage pins that provides 0.8mm clearance. Applications include a power distribution box, body control module, and DC/DC converters. The TPS1211-Q1 devices are AEC-Q100 qualified for automotive applications.
