Automotive qualified LDOS support direct-to-battery use
A total of 17 AEC-Q100-qualified, high-voltage LDOs from Texas Instruments support applications that connect directly to a car or lorry battery, such as cluster, power steering and infotainment systems, door modules and lighting controls. The TPS7A16xx-Q1 with 60V input, TPS7A66xx-Q1 and TPS7B67xx families, and the TPS7B4250-Q1 LDO have low quiescent current, down to 10µA in standby mode extends battery life. Internal ESR (equivalent series resistance) compensation for a range of output capacitors, including ceramic, to be used, to reduce system cost and increase stability, says the company. The LDOs support input voltages of up to 40V for normal operation and up to 45V to support transient spikes in automotive designs. The TPS7A1601-Q1 can support up to 60V normal operation for trucks and heavy-duty equipment. A tracking function provides close to zero tolerance between on-board and off-board power supplies and helps customers get more accurate data from the off-board sensors. The TPS7A16xx-Q1 and TPS7A66xx-Q1 LDOs are available in an 8pin MSOP-PowerPad packages. The TPS7B67xx-Q1 LDOs are available in a 20pin HTSSOP.
