TB67S285FTG,EL Toshiba

TB67S285FTG Toshiba BiCD process integrated circuit silicon monolithic TB67S285FTG Active Gain Control Serial control Bipolar stepping motor driver The TB67S285FTG is a 3-wire serial controlled bipolar stepping motor driver with a built-in Active Gain Control architecture. The TB67S285FTG also has an internal current feedback control (ACDS) which enables the driver to control the motor current without using a sense resistor. Using the BiCD process, the TB67S285FTG is rated at 50 V, 3.0 A. P-VQFN48-0707-0.50-004 Weight: 0.14 g (typ.) Features Built-in Anti-stall architecture (AGC: Active Gain Control) Built-in sense resistor less current control architecture (ACDS: Advanced Current Detection System) Low Rds (on) MOSFET (High side+ Low side=0.4 (typ.)) Built-in serial-parallel convert circuit Serial output function for cascade connection 4 bit (16 steps) adjustable torque function Multi error detect functions (Thermal shutdown (TSD), Over currentdet ection (ISD), Power-on-reset (POR), Motor load open (OPD)) Error detection status output (Error Output) Internal VCC (5 V) regulator enables the driver to operate with a single power supply (VM). Adjustable constant current PWM frequency using external components Small package with thermal pad on back side (QFN48: 7.0 mm x 7.0 mm) Note: Please consider the heat condition when using the TB67S285FTG. 1 2017-09-15 2017 Toshiba Electronic Devices & Storage Corporation TB67S285FTG Pin assignment (Top View) 34 33 32 31 30 29 28 27 26 25 36 35 24 OUTB+ COUT 37 23 OUTB+ LOUT 38 22 RSBGND DATA 39 21 RSBGND CLOCK 40 20 OUTB- LATCH 41 19 OUTB- CLR 42 TB67S285FTG GATE 18 OUTA- 43 NC 17 OUTA- 44 STANDBY 16 RSAGND 45 NC 15 RSAGND 46 LO1 14 OUTA+ 47 13 OUTA+ LO2 48 1 2 3 4 5 6 7 8 9 10 11 12 Note Please solder the corner pad and the rear thermal pad of the QFN package, to the GND pattern of the PCB. 2 2017-09-15 AGC0 DOUT AGC1 OSCM CLIM0 VCC CLIM1 VCC FLIM VREFA VREFB BOOST LTH GND GND GND NC NC VMA VMB VMA VMB NC NC
