Description

The A3992SB-T is a kind of DMOS dual full-bridge microstepping PWM motor driver. It is designed for pulse width modulated (PWM) current control of bipolar microstepped stepper motors. Besides, internal circuit protection includes short-to-ground, shorted load, thermal shutdown with hysteresis, and crossover current protection. It is available in 24 pin batwing DIP package.

There are some features of A3992SB-T as follows: (1)±1.5 A, 50 V continuous output rating; (2)low RDS(on) DMOS output drivers; (3)short-to-ground protection; (4)shorted load protection; (5)optimized microstepping via six bit linear DACs; (6)programmable mixed, fast, and slow current decay modes; (7)4 MHz internal oscillator for digital timing; (8)serial interface controls chip functions; (9)synchronous rectification for low power dissipation; (10)internal UVLO and thermal shutdown circuitry; (11)crossover-current protection; (12)inputs compatible with 5 or 3.3 V control signals; (13)sleep and idle modes.

What comes next is about the maximum ratingsof A3992SB-T: (1)load supply voltage, VBB: 50 V; (2)output current, IOUT: ±1.5 A; (3)logic supply voltage, VDD: 7.0 V; (4)logic input voltage range, VIN: 0.3 to VDD + 0.3 V; (5)VBBx to OUTx voltage: 50 V; (6)OUTx to SENSEx Voltage: 50 V; (7)REF reference voltage, VREF: 3 V; (8)SENSE Voltage (dc), VSENSE: 500 mV; (9)operating ambient temperature,TA: 20 to 85; (10)maximum junction temperature, TJ(max): 150; (11)storage temperature, Tstg: 55 to 150.
