Description
The STDRIVE101 is a low voltage gate driver suitable for driving three-phase brushless motors.
It is a single-chip with three half-bridge gate drivers for N-channel power MOSFETs. Each driver has a current capability of 600 mA (sink/source). It integrates a low drop linear
regulator generating the supply voltage for both low-side and high-side gate drivers through a bootstrap circuitry.
The device provides Under Voltage Lock Out (UVLO) on both the low-side and high-side sections, preventing the power switches from operating in low efficiency or dangerous conditions.
The control logic integrated into the STDRIVE101 allows two input strategies (highside and low-side or enable and PWM driving sign...
