STDRIVE101 Datasheet Triple half-bridge gate driver Product status link STDRIVE101 Product label Features Operating voltage from 5.5 to 75 V 600 mA sink/source current capability 3.3 V and 5 V control logic Two input strategies: – ENx/INx with adjustable deadtime generation – INHx/INLx with interlocking Matched propagation delay for all channels Very short propagation delay: 40 ns Integrated bootstrap diodes 12 V LDO linear regulator (50 mA max.) Embedded VDS monitor for each external MOSFET Overcurrent comparator UVLO and thermal shutdown protection Standby mode for low current consumption operation Application Home automation and appliances e-bikes Power tools Fans and pumps Industrial automation Textile machines Gaming and consoles 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...
