Built-in elements assist scale back scale back the invoice of supplies and built-in sturdy security characteristic is offered

Optimising efficiency for low-voltage industrial functions as much as 75V, the STDRIVE101, an built-in three-phase half-bridge driver IC delivers a space-efficient and power-saving answer to manage three-phase brushless motors in e-bikes, energy instruments, pumps, followers, gentle equipment, gaming consoles and different tools.

The STDRIVE101 embeds three half-bridge drivers for exterior N-Channel MOSFETs, every in a position to sink and supply as much as 600mA gate present. Built-in bootstrap diodes and a 50mA 12V low-dropout (LDO) regulator prepared to produce exterior elements scale back the invoice of supplies. A comparator for over-current detection utilizing exterior resistors and drain-source voltage monitoring of every MOSFET for short-circuit safety are additionally offered.

Constructed-in security options embrace internally generated dead-time to forestall cross-conduction, over-temperature shutdown and Below-Voltage Lockout (UVLO) on each the low-side and high-side sections to forestall the MOSFETs from working in low effectivity or harmful situations.

A DT/MODE choice pin permits choices for management switching with particular person high-side and low-side indicators or a single PWM sign and allow enter. A standby pin units the STDRIVE101 in a low-power mode with the LDO turned off to maximise vitality financial savings when idle.

The STDRIVE101 is in manufacturing now and accessible in a 24-pin VFQFN 4mm x 4mm package deal from STMicroelectronics.
