Data sheet:
Material Declaration:
The STDRIVE102BH and the STDRIVE102H are triple half-bridge gate drivers suitable for 3-phase brushless motor driving.
The STDRIVE102BH/H is the optimal solution for battery supplied motor driver applications such as power tools, vacuum cleaner and small appliances thanks to its very efficient stand-by mode, that strongly reduce the current consumption when the device is not active.
The gate drivers are designed to drive, with a programmable gate current, six external N-channel power MOSFETs, allowing a superior performance of the power stage and regulating the slew rate of power outputs without the need of external gate resistors. The different configurations of the drivers can be selected through two analog pins (IGATE and TCC).
An integrated charge pump supplies the three high-side drivers, enabling unlimited on-time of the high-side MOSFETs.
An embedded 12 V LDO linear regulator provides the supply of the three low-side drivers and its output is available on the VCC pin, to also supply external loads.
Another LDO linear regulator provides a 3.3 V on the VDD pin to supply external low-voltage components and the embedded analog front-end (AFE), which has a different configuration, depending on the device part number: the STDRIVE102BH integrates three operational amplifiers and three comparators, the STDRIVE102H integrates one operational amplifier and two comparators. In a typical application, the operational amplifiers can be used to monitor the voltage across the shunt resistor(s) sensing the current flowing in the motor phases. Concurrently, the comparators can be used to detect dangerous overcurrent conditions.
A full set of embedded protections is present to increase the overall application robustness: undervoltage lockout (UVLO) on each supply (VCC, VDD, and charge pump voltage), thermal shutdown, and a VDS monitoring on both high-side and low-side MOSFETs. In case a protection is triggered, the nFAULT open-drain pin signals the event. The STDRIVE102BH has another dedicated open-drain pin (FLAG) which indicates whether the gate driver supply VCC falls below the guard limit. The device integrates a smart shutdown function which allows immediate turn-off of the outputs of the gate driver in the case of fault, by minimizing the propagation delay between the fault detection event and the actual output switch-off.
In addition to the main supply pin (VS), the STDRIVE102BH/H has dedicated pin VM, which should be connected to the motor supply voltage, in correspondence of the drains of the high side N-channel MOSFETs. The VM pin is used for the integrated VDS monitoring as well as a reference voltage for the charge pump. To increase device’s flexibility, the VS and VM pin can operate at different voltages.
