Lineup Expansion of Brushed DC Motor Driver ICs for Automotive Applications

2022-11-30 | 반환

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has expanded the lineup by launching two brushed DC motor driver ICs for automotive applications, “TB9053FTG” and “TB9054FTG,” each of which has incorporated two output driver channels rated at 5 A[1].

The new products TB9053FTG and TB9054FTG have incorporated two output driver channels rated at 5 A[1] and two types of small QFN package (6.0 mm × 6.0 mm (typ.)) are offered. This reduces the mounting area, helping to reduce the size of systems. In addition, by connecting the two channels in parallel, the products can drive one channel rated at 10 A[1]. Furthermore, PWM control with its low H-bridge output ON-resistance of 200 mΩ[2] allows highly efficient motor drive. In addition, their daisy-chain connecting function for SPI communication and motor controlling function by using only SPI communication reduce MCU ports.

Notes:
[1] The motor current that can drive motors actually is limited by operating conditions such as ambient temperature and power supply voltage.
[2] @Tj=25 °C, Iout=3 A, VBAT=8 V

Applications

Automotive equipment
● Power train systems: Electronic throttle control using H-bridge in engine control, various valve control, etc.
● Chassis systems: Latch driving and housing for retractable door mirrors, door latches, etc.
● Others: Control circuits that use H-bridge/half-bridge circuits, etc.

Features

● Output driver: 2-channel drive, 1-channel drive rated at 10 A[1] using 2 channels connected in parallel, and 4-channel half-bridge drive
● Low H-bridge output ON-resistance: Ron (H + L) = 200 mΩ (typ.) @Tj=25 °C, Iout = 3 A, VBAT = 8 V
● SPI communication function: Daisy-chain connecting function and motor controlling function by using only SPI communication reduce the number of MCU ports and the size of system
