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.
