Description
The A3932 is a three-phase MOSFET controller for use with
bipolar brushless DC motors. Its high gate-current drive
capability allows driving a wide range of N-channel power
MOSFETs and can support motor supply voltages to 50 V.
Bootstrapped high-side drive blocks provide the floating
positive supplies for the gate drive and minimize the component
count normally required. The high-side circuitry also employs a
unique FET monitoring circuit that ensures the gate voltages are
at the proper levels before turn-on and during the ON cycle.
Internal fixed off-time PWM current-control circuitry can be
used to regulate the maximum load current to a desired value.
The peak load-current limit is set by the user’s selection of
an input reference voltage and external sensing resistor. The
fixed off-time pulse duration is set by a user-selected external
RC timing network. For added flexibility, the PWM input can
be used to provide speed/torque control, allowing the internal
current control circuit to set the maximum current limit.
Optional synchronous rectification is included. This feature will
short out the current path through the power MOSFET reverse
body diodes during the PWM off-cycle current decay. This can
minimize power dissipation in the power MOSFET, eliminate
the need for external power clamp diodes, and potentially allow
more economical choices for the MOSFET application.
Packages
38-pin TSSOP (suffix LD)
The A3932 includes the commutation logic for Hall sensors
configured for 120 degree spacing. Power MOSFET protection
features include bootstrap capacitor charging current monitor,
undervoltage monitor, motor-lead short-to-ground, and thermal
shutdown.
The ‘–S–’ part-number suffix indicates an operating temperature
range of -20°C to +85°C. The ‘–LD–’ suffix indicates a 38-lead
TSSOP package. The initial ‘–TR–’ variant suffix indicates
tape and reel packing. The ‘–T’ final variant suffix indicates
lead (Pb) free composition, with 100% matte tin leadframe
plating.

LED驱动电源如何分类才靠谱呢?
一、LED电源按驱动方式可以分为两大类: A. 恒流式: 1、恒流驱动电路驱动LED是很理想的,缺点就是价格较高. 2、恒流电路虽然不怕负载短路,但是严禁负载完全开路. 3、恒流驱动电路输出的电流是恒定 ......
