Product overview
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 (high-side and low-side or enable and PWM driving signals). The driving method is selected according to DT/MODE pin. In both cases, prevention from cross conduction is ensured by interlocking or internally generated deadtime.
The STDRIVE101 also features a VDS monitoring protection for each external MOSFET, thermal shutdown and can be put in the standby mode to reduce the power consumption.
The device is available in a VFQFPN 4x4 24 leads package option.
