4 Pin µP Voltage Supervisor with Manual Reset

October 2003

rev 1.0

Electrical Characteristics:

Unless otherwise noted, VCC is over the full voltage range, TA = -40°C to 105°C.

Typical values at TA = 25°C, VCC = 5V for L/M/J devices, VCC = 3.3V for T/S devices and VCC = 3V for R devices.

Notes:

1. Production testing done at TA = 25°C. Over-temperature specifications guaranteed by design only using six sigma design limits.

2. RESET output is active LOW for the ASM811 and RESET output is active HIGH for the ASM812.

3. Glitches of 100ns or less typically will not generate a reset pulse.
