9 / 13 page 9 of 13 Notice: The information in this document is subject to change without notice ASM690A / 692A ASM802L / 802M ASM805L 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. Parameter Symbol Conditions Min Typ Max Unit VCC, VBATT Voltage Range (Note 1) ASM69_AC, ASM802_C 1.1 5.5 V ASM805LC 1.1 5.5 ASM69_AE, ASM80__E 1.1 5.5 Supply Current Excluding IOUT IS ASM69_AC, ASM80__E 35 100 µA ASM69_AC, ASM802_C 35 100 ISUPPLY in Battery Backup Mode (Excluding IOUT) VCC = 0V, VBATT=2.8V TA = 25°C TA = TMIN to TMAX 1.0 5.0 µA VBATT Standby Current (Note 2) 5.5V>VCC>VBATT-0.2V TA = 25°C TA = TMIN to TMAX -0.1 -1.0 0.02 0.02 µA VOUT Output IOUT = 5mA VCC- 0.025 VCC-0.010 V IOUT = 50mA VCC-0.25 VCC-0.10 VOUT in Battery Backup Mode IOUT=250µA, VCC < VBATT-0.2V VBATT-0.1 VBATT-0.001 V Battery Switch Threshold, VCC to VBATT VCC < VRT Power Up Power Down 20 -20 mV Battery Switch over Hysteresis 40 mV Reset Threshold VRT ASM690A/802L/805L 4.50 4.65 4.75 V ASM692A, ASM802M 4.25 4.40 4.50 ASM802L, TA = 25°C, VCC falling 4.55 4.70 ASM802M, TA=25°C, VCC falling 4.30 4.45 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. |
