Taiwan Semiconductor offers alternative source for automotive-grade LDO regulators
Integrated AEC-Q100 qualified low dropout regulators (LDOs) require minimal external parts count and are offered in four configurations in heat-spreading SOP-8EP and TSSOP-14EP packages by Taiwan Semiconductor.
The TQL8xx family offers manufacturers a reliable alternative source for the critical linear regulators used in battery-driven automotive functions, including dashboard, cluster, climate control, fuel pump and advanced driver-assistance systems (ADAS). The regulators are suited for secondary supply applications where a regulated output is essential during very low-cranking voltage conditions.
They are designed for stability in automotive battery-connect applications. They maintain two per cent accuracy over a wide range of input voltages and a full operating temperature range of -40 to +125 degrees C. They are offered in models with fixed outputs of 3.3V or 5.V and feature typical dropout voltages of 70 to 80mV at IO=100mA.
The TQL8xx family’s four package configurations are the SOP-8EP package with ignition enable pin (only), the SOP-8EP-package with enable, reset and watchdog output; and reset threshold adjustment, the TSSOP-14EP package with enable, reset and watchdog output and reset threshold adjustment, finally there is the TSSOP-14EP package with enable, watchdog monitor input; watchdog output, reset threshold adjustment and program timing adjustment.
The AEC-qualifies devices are manufactured in-house and provide a viable alternate source for high-demand devices, commented Sam Wang, Taiwan Semiconductor’s vice president, products.
Available design resources include comprehensive datasheets and spice models for each component in the series.
Taiwan Semiconductor’s expanded product portfolio includes trench Schottky’s, MOSFETs, power transistors, LED driver ICs, analogue ICs and ESD protection devices. Production facilities are located in China and Taiwan. They are fully compliant with current automotive and environmental standards such as IATF16949, ISO9001 and ISO14001.
Taiwan Semiconductor products are used in an array of applications in the electronics industry including automotive, computer, consumer, industrial, telecomms and photovoltaic.
