Voltage Regulator System IC suits automotive applications

Integrated intelligent system power IC, EM6152, incorporates multi-mode windowed watchdog timer, reset logic, and 5 V LDO automotive voltage regulator. Supporting operation up to 40 V, it comes in 8-pin SO8 package with regulator current output up to 100 mA or PSOP-16 power package rated to 400 mA. IC operates over -40 to +125[degrees]C range and comes in 2 versions with 33% (V50) or 67% (V53) open watchdog window size and one version with CAN-bus sleep mode detector (V55).

COLORADO SPRINGS, Colorado - November 8, 2005 - EM Microelectronic, an electronic systems company of the Swatch Group, introduces the EM6152, a highly-integrated intelligent system power IC. The EM6152 is the only system power IC that incorporates a multi-mode windowed watchdog timer, reset logic and 5V low dropout automotive voltage regulator with up to 400mA output current capability. The EM6152 is automotive qualified according to AEC-Q100 and can support operation up to 40 volts. It comes in a compact 8-pin SO8 package (regulator current output up to 100mA) and PSOP-16 "power package" (current output up to 400mA). The EM6152 operates over the temperature range from -40 to +125 [degrees]C, making it compatible with the demanding temperature extremes in automotive and industrial environments. It is ideal for use in high-reliability and mission-critical applications.

"As more and more electronic modules and systems are used in a car, it becomes increasingly important to use low power voltage regulators with sleep mode in order to prevent draining the car battery," explains Mougahed Darwish, president of the management board of EM Microelectronic. "As a leader in the field of low power ICs and a dedicated supplier to the automotive industry, EM is proud to introduce the EM6152 which draws only 145uA quiescent current and features increased robustness against ESD and latch-up. In its 'power package', this circuit is particularly well-suited for applications where linear regulators cause excessive power dissipation.
