TB67H420FTG,EL Toshiba

TB67H420FTG Toshiba BiCD process integrated circuit silicon monolithic TB67H420FTG Brushed DC Motor driver with Dual H-bridge mode The TB67H420FTG is a brushed DC motor driver with sense resistor less current control. The internal H-bridge can be controlled independently, as a two brushed DC motor driver or a single stepping motor driver using the dual H-bridge mode. Fabricated with the BiCD process, the TB67H420FTG is P-VQFN48-0707-0.50-004 rated at 50 V, 9.0 A Weight 0.14 g (typ.) Features Supporting large current (9.0 A) and high voltage (50 V) brushed DC motor operation. Capable of driving two brushed DC motors using dual H-Bridge mode. Capable of driving one stepping motor using dual H-bridge mode. Built-in sense resistor less current control. (ACDS: Advanced Current Detection System) Low Rds (on) MOSFETs (High side+ Low side=0.33 (typ.)) Error detection features (Thermal shutdown (TSD), Over current detection (ISD), Power-on-reset (POR), and Motor load open detection (OPD)) Error detection signal output (Error Output) Internal VCC (5 V) regulator enables the driver to be operated with a single power supply (VM). Adjustable constant current PWM frequency using external components. Small package with thermal pad. (QFN48: 7.0 mm x 7.0 mm) Note: Please consider the heat condition when using the TB67H420FTG. 2017-2020 2020-10-16 1 Toshiba Electronic Devices & Storage Corporation TB67H420FTG Pin assignment 26 25 36 35 34 32 31 29 28 27 33 30 24 OUTB+ NC 37 23 OUTB+ NC 38 22 RSBGND PWMA 39 21 RSBGND PWMB 40 20 OUTB- INA1 41 19 OUTB- INA2 TB67H420FTG 42 (Top View) INB1 18 OUTA- 43 INB2 17 OUTA- 44 NC 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 bottom thermal pad of the QFN package, to the GND pattern of the PCB.
