STMicroelectronics’ automotive-qualified micro-power op amp
Summary
The high maximum temperature enables use inside sensor control units (SCUs) placed close to sensors installed in the hottest areas for optimum measurement accuracy. In less extreme environments the TSU111H, with its extended temperature range, allows a mission profile up to three times longer than an equivalent Grade-1 device qualified at 125°C. This is suitable for applications such as the battery-management system (BMS) of hybrid and electric vehicles, which is never turned off and must consume the least possible power. A typical use is to enable precision measurements in the vehicle’s on-board charger (OBC). The device is included in ST’s 10-year longevity programme that ensures long-term product availability for automotive and industrial projects.
