TPD4125K Datasheet | Toshiba

TOSHIBA Intelligent Power Device High Voltage Monolithic Silicon Power IC .. The TPD4125K is a DC brush less motor driver using high voltage PWM control. It is fabricated by high voltage SOI process. It is three-shunt resistor circuit for current sensing. It contains level shift high-side driver, low-side driver, IGBT outputs, FRDs and protective functions for under voltage protection circuits and thermal shutdown circuit. It is easy to control a DC brush less motor by just putting logic inputs from a MPU or motor controller to the TPD4125K. HDIP26-P-1332-2.00 Weight : 3.8 g (typ.) Features - - - - - - - - - - High voltage power side and low voltage signal side terminal are separated. It is the best for current sensing in three shunt resistance. Bootstrap circuit gives simple high-side supply. Bootstrap diodes are built in. A dead time can be set as a minimum of 1.4 μs, and it is the best for a Sine-wave from drive. 3-phase bridge output using IGBTs. FRDs are built in. Included over-current and under-voltage protection, and thermal shutdown. The regulator of 7V (typ.) is built in. Package: 26-pin DIP. This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product, ensure that the environment is protected against electrostatic discharge. 2008-05-13 Marking GND 1 NC 2 NC 3 HU 4 HV 5 HW 6 LU 7 LV 8 LW 9 RS 10 DIAG 11 NC 12 VREG 13 NC 14 VCC 15 GND 16 19 IS1 25 W 24 BSW 26 IS3 23 VBB Pin Assignment Part No. (or abbreviation code) TPD4123K TPD4125K Lot Code.
