The IMP1810 supply voltage monitor is an improved, low-power replacement for the Dallas Semiconductor DS1810. Maximum supply current over temperature is a low 20µA, representing 50 percent lower power as compared to the DS1810.

The IMP1810 issues an active LOW reset signal whenever the monitored supply is out-of-tolerance. A precision reference and comparator circuit monitor power supply (VCC) level. Tolerance level options are 5-, 10- and 15-percent. When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces an active LOW reset signal.

After VCCreturns to an in-tolerance condition, the reset signal remains active for 150ms to allow the power supply and system microprocessor to stabilize.

The IMP1810 is designed with a push-pull output stage and operates over the extended industrial temperature range. Devices are available in compact surface mount SOT-23 packages.

Other low power products in this family include the IMP1811/12/15/16/17, IMP1233D and IMP1233M.

Application Information

Operation – Power Monitor

The DS1810 detects out-of-tolerance power supply conditions. It resets a processor during power-up, power-down and issues a reset to the system processor when the monitored power supply voltage is below the reset threshold. When an out-of-tolerance VCC

voltage is detected, the RESET signal is asserted. On power-up, RESET is kept active (LOW) for approximately 150ms after the power supply voltage has reached the selected tolerance. This allows the power supply and microprocessor to stabilize before RESET is released.

Output Conditions

The IMP1810 active LOW reset signal is valid as long as VCC

remains above 1.2V. The RESET output on the IMP1810 uses a push-pull drive stage that can maintain a valid output below 1.2V.

To sink current with VCCbelow 1.2V, a resistor can be connected from the reset pin (RESET) to Ground (see Figure 1). This configuration will give a valid value on the RESET output with VCC

approaching 0V. During both power up and down, this configuration will draw current when RESET is in the high state. A value of 100kΩ should be adequate to maintain a valid condition.
