Packaged in a PG-LQFP-64-27 (LQFP-64-EP, 10x10 mm) with exposed thermal pad, it provides non-inverting outputs, integrated current-sense amplifier, and ISO 26262 functional-safety support. Source/sink capability is 1 A typical with a 5.5 V to 60 V supply range and up to 90 V transient tolerance on bridge/motor/supply pins, suiting 48 V mild-hybrid architectures. A half-bridge gate driver is a power-management IC that translates low-power PWM logic signals from a microcontroller into high-current gate-drive voltages capable of rapidly switching large power MOSFETs. It sits between the MCU (control domain) and the inverter power stage (power domain), forming one of the cornerstones of every modern motor-drive or DC-DC converter. The TLE9180 family extends this concept with built-in protection, current sensing and ASIL-aware diagnostics, removing many external components. Key features include six half-bridge channels, programmable dead-time control, integrated charge-pump ready for 100% PWM duty, 5.5 V to 60 V supply range, current-sense amplifier for shunt-based phase-current measurement, and a comprehensive protection set: under-voltage, over-voltage, over-temperature, short-circuit, and cross-conduction prevention. SPI interface provides configurable fault and diagnostic readback. The LQFP-64-EP package exposes a thermal pad that drops theta_JA well below a standard LQFP, easing thermal design at 1 A continuous gate current. Typical applications include 12V/24V/48V BLDC and PMSM motor drives for electric water pumps, oil pumps, fans, HVAC blowers, e-bike traction controllers, and mild-hybrid auxiliary drives. Designers also use it for high-current three-phase solenoid drivers and DC-DC converter synchronous-rectifier control. The 90 V transient tolerance provides headroom for load-dump events in 24 V truck systems. When designing with this IC, ensure the bootstrap capacitors are sized for the maximum PWM period to maintain VGS above the MOSFET Miller plateau. The exposed pad must be soldered to a continuous ground copper pour to keep junction temperature within the -40C to +150C automotive Grade-1 range. Use the SPI window for cyclic diagnostics to meet ASIL requirements.

It integrates two half-bridge MOSFET outputs with RDS(on) < 100 mOhm per switch, supports an operating voltage range of 5.0 V to 28 V, and offers fully 3.3 V / 5.5 V compatible logic inputs. PWM/DIR control reduces the number of PWM-capable pins needed on the microcontroller side, and outputs can be pulse-width modulated at frequencies up to 20 kHz with a current limitation threshold of 8 A. An H-bridge (full bridge) motor driver is a type of integrated power stage that uses four switching elements arranged in an H topology to drive a bidirectional DC load (such as a brushed DC motor) from a single supply rail. H-bridge drivers belong to the broader category of motor drivers and motion-control ICs, which in turn fall under power management semiconductors used to interface low-power microcontrollers with high-current electromechanical actuators. By integrating the power FETs, gate drivers, and protection logic into a single IC, the TLE9201SGAUMA1 replaces discrete MOSFET bridges and significantly reduces PCB area and design complexity. Key features include short-circuit protection, over-temperature shutdown, low standby current, SPI-configurable diagnostics, and AEC-Q100 qualification for automotive use. The device also supports load currents above the current limitation threshold (8 A) by entering a fold-back / hiccup mode rather than latching off, allowing sustained fault handling in harsh environments. The TLE9201SGAUMA1 uses an N-channel MOSFET output stage with charge-pump gate drive, enabling low RDS(on) and high efficiency at low VIN. SPI diagnostics provide real-time feedback on fault conditions such as open load, short to battery, short to ground, and over-temperature. The integrated dead-time generation prevents cross-conduction of the high-side and low-side FETs during switching transitions, a critical reliability feature for H-bridge designs. Typical applications include throttle body control, HVAC flaps, mirror adjustment, headlight leveling, and small DC pumps in vehicles, as well as industrial valves, power tools, building automation, and small medical pumps. Any 12 V or 24 V brushed DC motor up to 6 A continuous current is a suitable load for this driver. When designing with this device, ensure that the exposed thermal pad (pin 12) is soldered to a sufficient copper area (at least 1 square inch on a 2-layer board) to keep junction temperature within SOA limits. Place the supply bypass capacitors (typically 100 nF ceramic plus 10 uF bulk) as close as possible to the VBB pin to suppress the high di/dt transients typical of PWM motor switching.
