µP Power Supply Supervisor With Battery Backup Switch

rev 1.0

October 2003

Electrical Characteristics:

Unless other wise noted, VCC = 4.75V to 5.5V for the ASM690A / ASM802L / ASM805L and VCC = 4.5V to 5.5V for the ASM692A / ASM802M;

VBATT = 2.8V; and TA = TMIN to TMAX.

Notes:

1. If VCC or VBATT is 0V, the other must be greater than 2.0V.

2. Battery charging-current is “-”. Battery discharge current is “+”.

3. WDI is guaranteed to be in an intermediate level state if WDI is floating and VCC is within the operating voltage range. WDI

input impedance is 50 k

Ω. WDI is biased to 0.3VCC.
