ZMDI Announces Power Management ICsAugust 7, 2012
The ZSPM4121 and ZSPM4141 ICs target applications requiring ultra-low-power operations.
DRESDEN, Germany /PRNewswire/ -- Zentrum Mikroelektronik Dresden AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling energy-efficient solutions, announces the release of the ZSPM4121 and ZSPM4141. As a global supplier of analog and mixed-signal solutions for automotive, industrial, medical, information technology, and consumer applications, ZMDI is pleased to introduce this class-leading family of ultra-low power, low drop-out (LDO) regulators and under-voltage battery protection switches. With standby power consumption of 20 nA for the ZSPM4141 and 70 nA for the ZSPM4121, they are "truly in a league of their own."
The ZSPM4121 protects batteries from destructive discharge by connecting or disconnecting the battery from the load based on a set threshold voltage. Even during the off-mode, charger current can be delivered to the battery through the ZSPM4121's internal Schottky diode. In this off-mode state, the ZSPM4121 will only draw 100 pA standby current (Iqq-off). With its low on-mode standby current of only 70 nA, the ZSPM4121 is perfectly suited for voltage monitoring in conventional or solar trickle-charging applications. The open-drain, pull-down power-good-not pin allows connecting an LED for power-good indication. The factory-programmable threshold voltage from 1.2 V to 4.2 V (in 100 mV steps) gives the ZSPM4121 a wide application range. The integrated over-current protection (3 A) eliminates external components, minimizing the application footprint and engineering effort.
The ZSPM4141 is an ultra-low-power LDO capable of driving up to 200 mA while consuming only 20 nA in standby and 100 pA in power-down mode. Its power consumption is up to 100 times lower than conventional LDOs. The ZSPM4141 is a perfect match for any battery-operated application, extending battery life to its maximum. A wide Vin range of 2.5 V to 5.5 V and voltage output of 1.2 V to 4.2 V (factory-programmable in 100 mV steps) provide maximum application flexibility.
"ZMDI is a market leader, developing technologies that enable our customers to create systems that further optimize energy efficiency, system operation, and battery life. The ZSPM4121 and ZSPM4141 family of power management ICs truly benefits our customers by offering solutions for applications that require ultra-low power," stated Edward Lam, Vice President of Product Marketing and Business Development at ZMDI.
